SD_SEND_STATUS	Send the SD card status
SD_SEND_WR_BLOCKS	Send the number of written clocks
SD_SET_ERASE_COUNT	Set the number of blocks to pre-erase
SD_SENDOP_COND	Send the OCR register (init)
SD_CLEAR_CARD_DET	Set or clear the 50K detect pullup
SD_SEND_SCR	Send the SD configuration register
SD_INVALID_APP_CMD	Invalid SD application command

Definition at line 141 of file lpc_sdmmc.h.
