FIG. 21 schematically shows a pin map in the SD mode and the SPI mode defined by the SDIO standard together with the embodiment of the present invention.

The connector 340 and the memory card socket 1170 included in the flip-type cover 100 and the portable electronic device 200 according to yet another aspect of the present invention may be manufactured to conform to an interface of a specific standard specification have. However, the connector 340 including the bridge 1510 shown in FIG. 21 is an example for illustrating the embodiment related to FIG. 20 to FIG. 24, and the embodiment of the present invention is not limited by FIG. 21 . That is, in the other embodiments (for example, see FIGS. 16A to 18B), the description about FIG. 20 to FIG. 24 may be applied to the SDIO standard.

The memory card socket conforms to the SDIO standard and can accommodate the memory card. SDIO standard can support operation of 1 bit SD mode, 4 bit SD mode and SPI (Serial Peripheral Interface) mode and can support 8 multiple slots according to SDIO standard interface control module. For example, a connector and a memory card socket according to the SDIO standard may be connecting one to four data lines, a clock line, a command line, a ground, a power supply line, or an interrupt line.

Referring to FIG. 21, the bridge 1510 may include eight pins 1511 according to the SDIO standard. The operation / function assigned to each of the eight pins 1511 in the 4-bit SD mode and the SPI mode according to the SDIO standard is as shown in FIG. Eight pins 1511 may be electrically connected to a plurality of connection pins (not shown) mounted on the portable electronic device.

The flip-type cover and the portable electronic device according to the other aspect of the present invention may be assigned additional operation / function to pins 1 and 8 assigned to RSV (Reserved) pins in SPI mode. For example, Pin 1 may be assigned a Chip Select (CS) operation / function. Further, the pin 8 may be assigned an operation / function for detecting a voltage level for discrimination of a connector or a memory card inserted into a memory card socket. The detected voltage level can be determined to be either Low (L) or High (H). When the voltage level is L, the host control unit 230 may determine that the flip-type cover is electrically connected to the portable electronic device. The host control unit 230 can determine that a memory card (for example, a T (Trans) -Flash card) is inserted when the voltage level is H. Hereinafter, a case where a chip select (CS) operation / function is assigned to pin 1 and an operation / function for detecting a voltage level is assigned to pin 8 will be described as an example. For the convenience of explanation, the operation / function of the pin 1 is referred to as "CS 2", and the operation / function of the pin 2 is referred to as "CS 1" in order to distinguish it from the pin 2.

However, unlike the above example, an operation / function for detecting a voltage level may be assigned to pin 1, and a Chip Select (CS) operation / function may be assigned to pin 8.

22 is a flowchart exemplarily showing a method of controlling a flip-type cover and a portable electronic device according to yet another aspect of the present invention.

22, the host control unit 230 can detect whether the memory card 455 or the memory card connector 1140 is inserted into the memory card socket 1170 of the portable electronic device 200 (S2401). It can be controlled to be performed by a memory card detect pin (for example, a T-flash detect pin, not shown) included in the memory card socket 1170. When the voltage level of the memory card detection pin (not shown) is detected as Low (L), the host control unit 230 can supply power to the memory card socket 370 (S2403). The step S2401 may be to detect the voltage level of the memory card socket 370 and judge only whether or not the memory card 455 or the memory card connector 1140 inserted in the memory card socket 370 exists. Thus, the purpose of the operation / function performed by the memory card detection pin may be different from the purpose of the operation / function performed by the pin 8.

The host control unit 230 may control the state of the pin 8 after step S2403 (S2405). The host control unit 230 can detect whether or not the voltage level of the pin 8 is L (S2407). If it is determined that the voltage level of the pin 8 is L, the host control unit 230 may determine that the flip-type cover 100 is connected (S2411). When the voltage level of the pin 8 is detected as H, the host control unit 230 may determine that a memory card (for example, a T-flash card 455) is inserted (S2411). If the voltage level of the pin 8 is detected as H, the SDIO card initialization (SDIO card initialization) may be performed for data transmission / reception with the inserted memory card (S2409). The SDIO card initialization may be performed according to the initialization algorithm defined in the SDIO standard.

The host controller 230 performs operations / functions for determining whether or not the memory card 455 exists in the memory card socket 350 of the flip-type cover 100 when it is determined that the flip-type cover 100 is connected . To this end, the host controller 230 may perform SDIO card initialization (SDIO card initialization). As in step S2409, the initialization of the SDIO card may be performed according to the initialization algorithm defined in accordance with the SDIO standard.

As a result of initialization in step S2413, the host control unit 230 may determine whether an initialization error has occurred (S2415).

If an initialization error has occurred, the host control unit 230 can determine that only the display module exists in the flip-type cover 100 (S2421). That is, the host control unit 230 can determine that the memory card is not inserted into the memory card socket 350 of the flip-type cover 100. Accordingly, the host control unit 230 can control the display module 140 and the portable electronic device 200 to communicate using the CS 2 (pin 1) as shown in FIG. To this end, the host controller 230 may control to select the display module 170 using CS 2 (pin 1) as shown in FIG.

If no initialization error has occurred, the host controller 230 may determine that both the display module and the memory card are present in the flip-type cover 100 (S2427). That is, the host control unit 230 can determine that the memory card is inserted into the memory card socket 350 of the flip-type cover 100. Accordingly, the host control unit 230 can control the display module 140 and the portable electronic device 200 to communicate using the CS 2 (pin 1) as shown in FIG. It is also possible to control the portable electronic device 200 to communicate with the memory card 455 inserted into the memory card socket 350 of the flip cover 100 using the CS 1 (pin 2). The host control unit 230 may control the display module 170 to select the display module 170 using CS 2 (pin 1) in order to communicate with the display module 170. It is also possible to control the selection of the memory card interface 150 of the flip-type cover 100 using CS 1 (pin 2) to communicate with the memory card inserted in the memory card socket 350 of the flip- have.

20 to 24, the operation / functions of the flip-type cover 100 are controlled by the host control unit 230 of the portable electronic device 200 so that the physical space of the flip- Saving and a manufacturing cost saving effect can be generated.
