MMC/SD/SDIO Socket (P5)
The SB-A510 MMC/SD/SDIO interface is based on the SD-0 interface of the CM-A510. The MMC
controller signals are routed to the standard MMC/SD socket (P5).
P5 power is supplied by the VCC_MMC voltage rail. VCC_MMC can be enabled/disabled by
GPIO13 on the on-board I2C GPIO extender IC.
The write protect signal of the MMC/SD/SDIO socket, “MMC_WP”, is routed to GPIO10 on the on-
board I2C GPIO extender.
