Implementations

source

impl R

source

pub fn dten(&self) -> DTEN_R

Bit 0 - Data transfer enable bit This bit can only be written by firmware when DPSM is inactive (DPSMACT = 0). This bit is cleared by Hardware when data transfer completes. This bit shall only be used to transfer data when no associated data transfer command is used, i.e. shall not be used with SD or eMMC cards.

source

pub fn dtdir(&self) -> DTDIR_R

Bit 1 - Data transfer direction selection This bit can only be written by firmware when DPSM is inactive (DPSMACT = 0).

source

pub fn dtmode(&self) -> DTMODE_R

Bits 2:3 - Data transfer mode selection. This bit can only be written by firmware when DPSM is inactive (DPSMACT = 0).

source

pub fn dblocksize(&self) -> DBLOCKSIZE_R

Bits 4:7 - Data block size This bit can only be written by firmware when DPSM is inactive (DPSMACT = 0). Define the data block length when the block data transfer mode is selected: When DATALENGTH is not a multiple of DBLOCKSIZE, the transfered data is truncated at a multiple of DBLOCKSIZE. (Any remain data will not be transfered.) When DDR = 1, DBLOCKSIZE = 0000 shall not be used. (No data will be transfered)

source

pub fn rwstart(&self) -> RWSTART_R

Bit 8 - Read wait start. If this bit is set, read wait operation starts.

source

pub fn rwstop(&self) -> RWSTOP_R

Bit 9 - Read wait stop This bit is written by firmware and auto cleared by hardware when the DPSM moves from the READ_WAIT state to the WAIT_R or IDLE state.

source

pub fn rwmod(&self) -> RWMOD_R

Bit 10 - Read wait mode. This bit can only be written by firmware when DPSM is inactive (DPSMACT = 0).

source

pub fn sdioen(&self) -> SDIOEN_R

Bit 11 - SD I/O interrupt enable functions This bit can only be written by firmware when DPSM is inactive (DPSMACT = 0). If this bit is set, the DPSM enables the SD I/O card specific interrupt operation.

source

pub fn bootacken(&self) -> BOOTACKEN_R

Bit 12 - Enable the reception of the boot acknowledgment. This bit can only be written by firmware when DPSM is inactive (DPSMACT = 0).

source

pub fn fiforst(&self) -> FIFORST_R

Bit 13 - FIFO reset, will flush any remaining data. This bit can only be written by firmware when IDMAEN= 0 and DPSM is active (DPSMACT = 1). This bit will only take effect when a transfer error or transfer hold occurs.
