Implementations

[src]

impl R

[src]

pub fn txdat(&self) -> TXDAT_R

Bits 0:15 - Transmit Data. This field provides from 1 to 16 bits of data to be transmitted.

[src]

pub fn txssel0_n(&self) -> TXSSEL0_N_R

Bit 16 - Transmit Slave Select. This field asserts SSEL0 in master mode. The output on the pin is active LOW by default. Remark: The active state of the SSEL0 pin is configured by bits in the CFG register.

[src]

pub fn txssel1_n(&self) -> TXSSEL1_N_R

Bit 17 - Transmit Slave Select. This field asserts SSEL1 in master mode. The output on the pin is active LOW by default. Remark: The active state of the SSEL1 pin is configured by bits in the CFG register.

[src]

pub fn txssel2_n(&self) -> TXSSEL2_N_R

Bit 18 - Transmit Slave Select. This field asserts SSEL2 in master mode. The output on the pin is active LOW by default. Remark: The active state of the SSEL2 pin is configured by bits in the CFG register.

[src]

pub fn txssel3_n(&self) -> TXSSEL3_N_R

Bit 19 - Transmit Slave Select. This field asserts SSEL3 in master mode. The output on the pin is active LOW by default. Remark: The active state of the SSEL3 pin is configured by bits in the CFG register.

[src]

pub fn eot(&self) -> EOT_R

Bit 20 - End of Transfer. The asserted SSEL will be deasserted at the end of a transfer, and remain so for at least the time specified by the Transfer_delay value in the DLY register.

[src]

pub fn eof(&self) -> EOF_R

Bit 21 - End of Frame. Between frames, a delay may be inserted, as defined by the FRAME_DELAY value in the DLY register. The end of a frame may not be particularly meaningful if the FRAME_DELAY value = 0. This control can be used as part of the support for frame lengths greater than 16 bits.

[src]

pub fn rxignore(&self) -> RXIGNORE_R

Bit 22 - Receive Ignore. This allows data to be transmitted using the SPI without the need to read unneeded data from the receiver.Setting this bit simplifies the transmit process and can be used with the DMA.

[src]

pub fn len(&self) -> LEN_R

Bits 24:27 - Data Length. Specifies the data length from 1 to 16 bits. Note that transfer lengths greater than 16 bits are supported by implementing multiple sequential transmits. 0x0 = Data transfer is 1 bit in length. 0x1 = Data transfer is 2 bits in length. 0x2 = Data transfer is 3 bits in length. … 0xF = Data transfer is 16 bits in length.
