The organization must have 5 sets of connectors. The number of connectors is the largest, resulting in higher connector cost and space. 1261788 Second, the use of pin and jack combined connection design, resulting in the insertion and withdrawal of the need for more strength. 2. When the positioning of the pin surface is not accurate, it is easy to cause the pin to be skewed and damaged. Fourth, the use of side-by-side bus design, when connecting multiple cards, the electronic application device must provide a separate start signal, can not run and even more 'card. 5. There is no anti-write protection design, and it is impossible to ensure that the memory content is not damaged. In the case of a SmartMedia card, the interface requires 22 sets of contacts, and the mechanism picks up the contact piece with the flat contact terminal. In addition, two sets of crystals are required as the detection memory card, whether to insert the positioning, and whether to stick the anti-write conductive sticker. The shortcomings of the smartMedia interface are as follows: 1. The system must have 22 sets of connection terminals, and the green film with the measurement position and the anti-write conductive sticker must have higher connector cost and space. Second, the connection terminal before and after the double row setting ‘When inserting or exiting, the first row contact position button is connected to the second row connection terminal, which causes instability during insertion. Third, the power connection signal VCC and GND are connected to the two sets of contact H, and it is easy to short-circuit between the terminals.

Four contacts can be arranged between the four contacts of the original USB; the plug-in structure of the sfmi interface of the present invention can be shared with the plug-in structure of the USB interface, and different plugs need to be configured separately. structure. Another feature of this interface is the 4-bit bidirectional bus bar, D〇 and D1 two sets of signal lines. When the electronic application device 1 uses a USB interface to connect the memory card, it is changed to (4) _ mode, shouting The D+ and D- signal lines required for the interface. It also supports the communication interface of the standard interface, so that it can be installed on a personal digital device or a digital device supporting the USB interface without any additional electronic application (10). The present invention also provides a multi-functional small memory card slot with a 4-pin and 8-pin design. The 4-pin design is used for the basic USB interface. The 8-pin design is used for the _ interface. The s introduction surface of the 8-pin position has four pins that are the same as the threat interface level, and the other four are inserted and distributed between the four-pin position. The slot is divided into a male slot and a female slot. Referring to Fig. 3, the main controller 22{) of the present invention comprises four components, a 1261788 I/〇 control 221, a memory controller 222, a formatter 223, and a - formatter 224. Wherein the 1/〇 main controller 221 is used to control the memory card, and 210 'includes the decision to operate the memory card 1/〇 function module ^ input mode operation or operate in output mode, or _ Interface or leg interface mode operation, etc. The memory main controller 222 is used to control the memory 230' and the formatter 223' and the deformatter (10) perform format conversion of the interface signal and the interface interface signal to match the memory card I/O function module. Operating poles. The current actions of the formatter 223, and the formatter will be described below. The system interface and the memory card are inserted into the detection signal: 'memory card insertion_recording, multi-function input and output control signal connected to the control chip in the memory cutting material, and the electronic application device 100 supporting the multifunctional small memory card interface Connected to the power supply via a resistor, in support of the (4) interface of the system side of the connection, the Wei Wei needle can be separated from the electronic device (10) _ interface, (4) sub-application device 1 〇〇 _ This signal achieves the versatility of whether the small memory card is inserted or positioned. ^Hidden card I / O ship module (4) measured · contains a power supply 310 ' - rib input _ end 32 〇, one (3) output tilt test end coffee, a first - 1261788 - polar body 360, - second two pole The body 370 is a first resistor 340 and a second resistor 350. The function of the memory card I/O function module determines whether the plug-in terminal is a USB interface or an SFMI interface by detecting the presence of the system interface and the memory card insertion detection signal (BD_CD). The small memory card is inserted into the electronic application device 100 supporting the small memory card interface. Since the electronic application device 1 continuously supplies power regardless of whether the small memory card is inserted or not, the small memory card should first maintain the CD signal when starting up. Impedance state, so as not to affect the BD-CD signal detection check action. Then, the status of the BD_CD signal is checked, and if the BD-CD signal status is high, it means that the system side supports the small memory card interface, and enters the small memory card interface operation mode. And then drive the output CD signal to a low potential, and notify the electronic application device 100 that the small memory card has been inserted and positioned; conversely, if the rib CD is low, it means that the BD-CD signal is not connected to the power supply through the resistor. The representative supports the USB interface and enters the USB interface operation mode. In the circuit shown in FIG. 4, the Vcc contact is connected to the power supply 31, and the system interface and the memory card insertion detection signal BD-CD are coupled to the BD input detection terminal 320 via the forwardly coupled first diode 360. The reversed-connected second diode 37 connects the CD output detection end, and the system interface and the memory card insertion detection signal 16 1261788 both the CD and the second resistor are connected to the ground terminal _, the Vcc and the system interface And connecting the first resistor to the fine signal inserted in the memory card. In the figure, the first resistance is 10 ΚΩ and the second resistance is ugly Ω, which is a preferred embodiment of the present invention, and other suitable values can also be used in the present day, without being limited to the # in the figure. χ佳贝 彳. The function of the first and second resistors is to boost BD-CD and Vcc to provide the required circuit operation. When the USB interface is inserted into the multi-function small memory card, referring to FIG. 4A, the first diode 360 will be turned on, and the rib input 32 is turned on, so that the speed can know that the inserted interface is the SFMI interface, and vice versa when the system interface When the memory card insertion detection signal BD-CD is not input, the first diode 36 is not turned on, so that the signal that is rounded is the USB interface signal. Conversely, in the output mode, when the output signal is the SFMI interface signal, the second diode 370 is turned on, and the known signal is the slap signal, and vice versa. Small memory card with multi-function communication interface: Multi-function small memory card interface adopts half-duplex, 4-bit stream mode, based on CLK signal, and each bit clock can transmit 4-bit information. The information transmission method is controlled by the electronic application device 1 and determines the data phase transmission length after the transmission command and the transmission length are issued. In order to improve the application of the interface and simplify the overall system design, the interface transmission is based on data packets. And the communication protocol uses the analog communication endpoint in the memory card as the source or sink of the information transmission. All the memory cards or 10 cards supporting the "multi-function small memory card interface" need at least Supports a set of communication endpoints, called "control endpoints" whose endpoint address is 0. The read/write device can obtain a detailed description of the memory card or the 10 card through the control terminal, learn the function and other communication endpoint settings, and perform appropriate settings, activate its function, and transmit the data. (1) Start bit/end bit_start bit / End bit When the electronic application device 100 and the memory card are used to start data transmission, they must be generated at the forefront of the data packet. The beginning position 兀 'adds two end periods of the clock period DO to D3 at the end of the billet packet. 2 Packet Flip Code—Paeket Identifier (pID) 凊 Refer to Figure 5, the communication packet self-packing packet identification code (10), and the type of identification code is different. Each-group# material seal contains 1.= package identification code: indicates the direction of the packet transmission data, the transmission endpoint address and the length of the material, 2. The data, which contains a set of data error 1261788 _ code '3·爿The packet status code 'receives the payload data' and returns the reception status confirmation data to be received correctly. The packet identification code_marking electronic application device 100 will perform the transmission of the data output. Packet identification code job No electronic application clothing 100 will carry out the data input transmission. The packet identification code 1101 indicates that the electronic_device (10) will set or obtain relevant information for the _ endpoint. The package is overwritten. _ The receiving end confirms the data packet and receives t. The packet identification code 1010 indicates that the information receiving end is temporarily unable to receive information, or the outgoing end is temporarily unable to transmit information. The packet identification code 111G indicates that the communication terminal "stops working" or the control terminal does not support the control command. PID identification total & 彳立元, in order to prevent communication errors, add 4 bits in reverse, form a total of 8 bits in ascending power, and divide the transmission twice in two sets of clocks. As shown in Figure 6. The receiving end receives the correct complete PID and PID, and PID = (PID,), which confirms that the received pid is correct. (3) Communication Endpoint - The Endpoint communication endpoint is a basic unit that supports a small memory card or a 10-card with a small memory card interface and an electronic application to transmit data. Corresponding to the individual small-size memory card or (1) card, the data buffer with a specific capacity size is used for temporarily storing the data carried by the communication package between the electronic application device 100 and the small memory card. A small memory card or 10 cards supporting a small memory card interface can support up to 16 communication endpoints, and specify the packets to be transmitted by the communication endpoint address in the communication packet. A small memory card or a 1-inch card that supports a small memory card interface must have at least one set of communication endpoints with the address set to 〇. After detecting the insertion of the small memory card through the small memory card interface, the electronic application device can obtain the identification code, the function form, the number of communication terminals, and the communication terminal of the small memory card through the communication terminal. Information about the address and the form of the communication endpoint. The communication endpoints are divided into the following four types, which are respectively applicable to different types of data transmission between the electronic application device 100 and a small memory card or a 1-inch card. Control Endpoint - A small memory card and a 1st card must have a set of control endpoints with an endpoint address of 0. The function of the control endpoint allows the electronic application device 100 to obtain information such as the identification code, the functional form of the small memory card, the number of communication terminals supported, the address of each communication endpoint, and the form of the communication endpoint when the small memory card is activated. Data Entry Endpoint - Used to allow the electronic application device 1 to input a large amount of data from a small memory card or 10 cards. Data Output Endpoint - Used to allow the electronic application device to output a large amount of 1261788 material to a small memory card. Status Interrupt Input Endpoint - Used to allow small memory card or 1 card setting. The electronic application device 100 is required to interrupt the input information from the small memory card or the 10-card input state by the setting period. As shown in FIG. 7, the transport indication packet specifies the communication endpoint corresponding to the subsequent data packet or status packet by indicating the communication endpoint. The communication endpoint transmits in the transmission indication packet by 4 bits, followed by the PID in the clock cycle. (4) Data length - Data Length As shown in Fig. 8, after ENDP, i2 bits representing the length of the DATA DATL are transmitted in 3 clock cycles. DATL takes 1 byte as the early position ' 0x000 for 4096 jUM triad, and the minimum value is 〇χ〇〇1 for 1 byte. (5) Remuneration data - the information (10) τ) actually carried by the Payload Data 1 packet and transmitted to the communication endpoint. DATL sets the salary (four) material length. During transmission, each station is separated by 2 gamma pulses. The direction of transmission is specified by the electronic application in the line J, as shown in Figure 9. The payload data is appended with the CRC16 error check code of the temple cycle. Among them, the algorithm CRC16 1261788 is divided by 2 and the remainder method can be further divided into two equations with G(1)=I. The data transmission sequence is as shown in FIG. - Packet Status Acknowledge After receiving the data - the party ' _ Jian Wei Wei finished, confirm that the inspection of the horse is in compliance with the woven fabric contact (four) is red. If the reception is completed correctly, it will be returned to the weaving. If the reception cannot be completed temporarily, or the inspection code indicates that there is an error in the data, it will be sent back to request retransmission. If the internal error of the memory card is incorrect or the result of the execution instruction is wrong, then the STALL . As shown in Figure 11. (7) Data format All communication packets are sent by the electronic application 1GG (pure end) to transmit the 'data packet _ sequence as the starting bit, packet identification code, communication endpoint 'data length, payload data The packet status code, data format, and end bit are initiated by the system to transmit data, and the packet identification code, the designated communication endpoint, and the data length are generated. If the packet belongs to the IN packet, if the device receives the above information, if it fails to generate the required data, it can respond to the device status code to stop the subsequent transmission, and can follow the bottle movement, again 2 = , 1261788 Data packet. If the device end can respond to the required data, the device generates a start bit, and then starts to return the information stored in the internal communication terminal of the device. After the data length required by the system is satisfied, The 16-bit CRC check code is added. After receiving the check code, the system can return the ACK after checking and confirming the error. If the data is incorrect, it will be sent back and the packet can be restarted to get the correct data. If the packet belongs to the OUT s SETUP packet, after the system completes the packet and recognizes the J code, the communication endpoint address, and the data length, the system then starts to import the incoming data, and the length of the data to be transmitted by the system is required. After that, the 16-digit CRC check code is added. After receiving the check code, the device can pass the S ACK after checking and confirming it. If the data is incorrect, it will be sent back to the ancestor, and the system-side master decides whether to decorate it. Kai _ package to (8) Control transmission mode electronic application 褒龙〇 can control the transmission mode, read the multi-function memory card related Wei from the preset transmission m, or set its related functions. Control transmission mode is divided into feet The p phase, the ΜΤΑ phase, and the s_s phase have the following format: In the SETUP phase, the system will send a SETUP packet containing the SETUP packet payload, the job security is ^, and the (4) button is the 8 bit 1261788 tuple, which is then sent by the system device. 8-bit SETUP instruction code and parameter and 2-byte CRC16, and finally the device side returns the status code to confirm whether the packet is received normally.
