sdmmc_init_mmc_bus_width() function

Read one byte from an SDIO card using IO_RW_DIRECT (CMD52)

Write one byte to an SDIO card using IO_RW_DIRECT (CMD52)

Print information about the card to a stream

Read multiple bytes from an SDIO card using IO_RW_EXTENDED (CMD53) This function performs read operation using CMD53 in byte mode. For block mode, see sdmmc_io_read_blocks. By default OP Code is set (incrementing address). To send CMD53 without this bit, OR the argument `addr` with `SDMMC_IO_FIXED_ADDR`.

Write multiple bytes to an SDIO card using IO_RW_EXTENDED (CMD53) This function performs write operation using CMD53 in byte mode. For block mode, see sdmmc_io_write_blocks. By default OP Code is set (incrementing address). To send CMD53 without this bit, OR the argument `addr` with `SDMMC_IO_FIXED_ADDR`.

Probe and initialize SD/MMC card using given host

Write given number of sectors to SD/MMC card

Read given number of sectors from the SD/MMC card

Erase given number of sectors from the SD/MMC card

Check if SD/MMC card supports discard

Read blocks of data from an SDIO card using IO_RW_EXTENDED (CMD53) This function performs read operation using CMD53 in block mode. For byte mode, see sdmmc_io_read_bytes. By default OP Code is set (incrementing address). To send CMD53 without this bit, OR the argument `addr` with `SDMMC_IO_FIXED_ADDR`.

Write blocks of data to an SDIO card using IO_RW_EXTENDED (CMD53) This function performs write operation using CMD53 in block mode. For byte mode, see sdmmc_io_write_bytes. By default OP Code is set (incrementing address). To send CMD53 without this bit, OR the argument `addr` with `SDMMC_IO_FIXED_ADDR`.

Block until an SDIO interrupt is received Slave uses D1 line to signal interrupt condition to the host. This function can be used to wait for the interrupt.

Get status of SD/MMC card

Check if SD/MMC card supports trim

Check if SD/MMC card supports sanitize

Get the data of CIS region of an SDIO card. You may provide a buffer not sufficient to store all the CIS data. In this case, this function stores as much data into your buffer as possible. Also, this function will try to get and return the size required for you.

Sanitize the data that was unmapped by a Discard command

Erase complete SD/MMC card

Enable SDIO interrupt in the SDMMC host
