Definition of SD Signals

The following table gives the definition of the SD signals. Note that the signal pins from the J2 pin

header share the same pin as the GPIO.

Signal Name Direction GPIO Description

SD_CLK Output GPIO 7 Clock signal to SD/MMC

SD_CMD Bidirectional GPIO 2 Bidirectional line for command and response

SD_DAT<3:0> Bidirectional GPIO <6:3> Bidirectional line for read and write data

SD_CD Input GPIO 1 Card detect

SD_WP Input GPIO 0 Write protect
