72 needle connector functional interpretations of table 9 automobile ECU special use

More than provided the main hardware the electric circuit constitute structure of control device and realized principle, the below will describe the course of work of system in detail.

(1) working-flow before and after the electrification reset.

Before system power-up, fibrous root is configured work according to using the difference that needs to control device, mainly is to finish the setting of wire jumper and the set of hardware configuration switch. Now illustrate as follows.

MODCK[1:3 among the S1] be set to " 010 " EN_CFG position reset. " 1 " expression conducting, " 0 " represents not conducting. The 2nd that puts S5 is one state, makes the CS1 conducting, chooses external SRAM. The 5th CS0 of S5 is set to one state, chooses outside FLASH.

After system powers on, through voltage-stablizer LT1374I5 input voltage is converted to 5V, for the chip of 5V power voltage supply on the electronic circuit board provides voltage. Through the voltage-stablizer LT1587-CT3.3 of fixing output 3.3V, be 3.3V voltage with the 5V voltage transitions again. Chip power supply for MPC555 microprocessor and 3.3V supply voltage. Arrive this, the electric power system of whole control device is finished.

When electrification reset operates, MPC555 will detect the low level input signal of PORESET, enter the electrification reset state after the affirmation, according to MODCK[1:3] signal determine crystal oscillator frequency, phaselocked loop (PLL:phase-locked loop) multiplier parameter, cycle interruption timer clock (PITRCLK) and time base clock source (TMBCLK). And MPC555 also confirms HRESET and the input of SRESET pin. When the rising edge of PORESET, will determine the state of MODCK pin, MODCK[1:3 in this example] be set to " 010 ", because the frequency of crystal oscillator is 4MHz, so the primary timing reference frequency is 4MHz, PLL is effective, and normal manipulation mode, multiplier parameter are 5, the TMBCLK clock is with 4 frequency divisions, and the PITRCLK clock is with 256 frequency divisions. Obtained system clock frequency this moment. After withdrawing from the electrification reset state, MPC555 will continue to drive HRESET and the SRESET pin continues 512 system clock cycles. After confirming the HRESET signal, in the sampling time (HRESET is low level), RSTCONF is identified, in this control device, the RSTCONF signal is determined by the EN_CFG position of hardware configuration switch S 1, the RSTCONF signal should be the high level input, and this moment, the 20th HC at the hardware reset configuration words register of MPC555 was 0, and system will start from external memory storage. This moment, reset configuration words was provided by the CMFCFIG register. Starting relevant position with device in this register has as follows:

The BDIS position is 0, and after expression resetted, Memory Controller Bank0 was activated, and the BR0 register is effective, and the CS0 chip selection signal of MPC555 is effective, and by the 5th bit switch gating CS0 of S5, system will start from FLASH.

The IP position is 0, and after expression resetted, the IP position in machine status register(MSR) (MSR) register equaled 0, and exception vector table will be from the physical address 0x00000000 beginning of FLASH. Because be the hardware reset operation, it is unusual to have produced system reset, according to exception vector table, program pointer should point to the 0x00000100 place, and system program should take this address as entrance, be carried out.

After the driving of SRESET pin was identified, the configuration of debug port will be from DSCK and the sampling of DSDI pin.

After 512 clock cycle, MPC555 stops to drive HRESET and SRESET pin, and the electrification reset operation is finished. In the operation of electrification reset, comprised that reseting logic and PLL state reset, system configuration resets, clock module resets, the HRESET pin drives, the debug port configuration, other internal logics reset and the SRESET pin drives.

More than with an example described system from power on before the switch configuration of hardware circuit and wire jumper work be set begin, to the signal flow direction and the associative operation of system power-on reset MPC555 microprocessor, and finish the overall process that resets. Main electrification reset mechanism when this example has also illustrated the work of this control device.

(2) memory operation flow process

For extending out the FLASH memory, we can be as seen from Table 10, reset, the pin state of FLASH chip during read and write operation.

When FLASH resetted, the RSET pin linked to each other with the HRESET pin of MPC555, and when confirming that MPC555 has reset operation, RSET is low level, and each pin state of FLASH device sees table 10 for details.

Annotate: " L " represents low level, and " H " represents high level, and "-" expression does not affect operation

The state of each pin during table 10FLASH storage operation

When reading the FLASH operation, the RD/WR of MPC555 and CS0 pin output low level signal driver FLASH memory OE, CE pin are low level. Address bus provides stable address signal, and the CE signal is used for choosing the FLASH memory, and OE is data output control signal, allows data output. The WE pin should keep exporting high level. At this moment, the data pin of FLASH memory will be exported active data, send the data pin of MPC555 microprocessor to by data/address bus, finish the receive data operation, namely data be read the address of appointment.

The write operation of FLASH comprises the programming of FLASH and erasable operation. WE and CE are driven to low level, and OE is high level.

Before explanation SRAM memory read/write cycle sequential, at first given the time response of read/write cycles by table 11.

Label	Describe	Minimum time	Maximum time	Chronomere
					t RC	Tead cycle time	12	-	Nanosecond
t AA	The address access time	-	12	Nanosecond
					t WC	Write cycle time	12	-	Nanosecond
t SA	Address Time Created	0	-	Nanosecond
					t PWE	Write pulse width	8	-	Nanosecond
t SD	Data are established to writes end	6	-	Nanosecond
					t HD	Write the data hold time after the end	0	-	Nanosecond

Table 11SRAM memory read/write characteristic cycle time

The read cycle sequential of SRAM requires such as Fig. 8, and at A point place, MPC555 send access unit address, from then on read cycle begins to calculate, and at tRC after the time, the data of reading are really stable at data/address bus, so require after address signal is effective, chip selection signal CE is effective. If after address signal was effective, CE can not in time arrive significant level, then probably only data occur at internal data bus, and data can not be delivered on the data/address bus of system. After the C point, the output data become effectively, and as long as address signal and output allow signal OE not cancel, export so data and will remain valid always. In the whole read cycle, the WE signal should keep high level.

The write cycle time sequential of SRAM requires such as Fig. 9, when write cycle time begins, one sector address tSA Time Created is arranged first, at B point place, address signal is effective, at this moment, MPC555 puts chip selection signal CE and write signal WE is low level, for data writing, as long as when CE and WE are low level, data can be stablized and get final product. Write cycle time tWC be exactly the A point to the time between the D point, it the time address tSA Time Created, write pulse width tPWE and write operation tHD three's recovery time sum.

(3) special-purpose 72 needle sockets of automobile ECU

As the control device of power assembly, need to communicate and transmission of control signals with other ECU continually, for this reason, we provide communication interface system in 72 needle sockets, comprise serial communication, CAN bus communication and to the support of two-port RAM. The below will introduce the course of work of these three kinds of communications in detail.

Serial communication:

In the built-in queues formula serial multi-channel module (QSMCM:Queued Serial Multi-Channel Module) of MPC555, dual serial communication interface submodule (SCI:Serial Communication Interface) is arranged, communicate with other ECU by universal serial bus and ancillary equipment. In the process of control device by SCI output data, MPC555 delivers to data in the parallel data output register of SCI (TDR:Transmit Data Register), then being transferred to serial sends in the shift register (serial shifter), serial shift register becomes serial data with the method for displacement with parallel data, then the pin TxD[1:2 by MPC555] be sent to the MAX233AEWP interface chip, the function of MAX233AEWP is that Transistor-Transistor Logic level is converted to RS-232 mouth level, can link to each other with serial ports of computers, sampled data is sent to computer in real time so that monitoring.

Serial communication adopts asynchronous sending mode, after the transmission of putting SCI control register (SCCR) allows position (TE) for " 1 ", just begins process of transmitting. After the reception of putting the SCCR register allows position (RE) for " 1 ", will begin receive data. Data transmission format is 10 frame formats (without strange/even parity bit) of 1 start bit, 8 bit data positions and 1 position of rest. The baud rate of transfer of data is 9600 bps.

The CAN bus communication:

Because built-in two CAN bus control unit TouCAN modules so need not external CAN controller chip in our control device, only need to connect the interface chip PCA82C250 of CAN bus control unit in the MPC555 microprocessor. The function of PCA82C250 interface chip is to provide differential receiving ability to the CAN controller, provides differential transmitting capacity to the CAN bus. The TouCAN module provides four pins, and A_CNTX0 and B_CNTX0 are the transmitting terminal of serial data, and A_CNRX0 and B_CNRX0 are the serial data input. 16 message buffers are provided in each TouCAN module, and each message buffer has the sending and receiving dual-use function, also has in addition the dual serial data buffer zone in the TouCAN module, is responsible for respectively the sending and receiving of data. Can only activate one of them at one time.

When sending data, the TouCAN module is sent data into serial data and is sent buffering area from message buffer, send through A_CNTX0, B_CNTX0 pin, send to the TxD pin of PCA82C250 interface chip, the CANH pin of process PCA82C250 chip sends to data on the CAN bus from 72 needle interfaces. When receive data, data on the CAN bus send to A_CNRX0, the B_CNRX0 end of TouCAN through PCA82C250 interface chip RxD pin, receive message buffer by the Serial data receiving buffering area of TouCAN module.

The support of two-port RAM interface:

The two-port RAM interface provides 8 position datawire D0～D7,11 bit address line A21～A31 and WR, CS and RD cooperating, the exchanges data of realization control device and other ECUs. The two-port RAM of DPRAM interface compatibility 2K and 1K, the two-port RAM write signal was effective when WR was low level, and when CS was low level, the two-port RAM chip selection signal was effective, and when RD was low level, the two-port RAM read signal was effective.
