Writer for register STAT

Methods

impl W

pub fn rxov(&mut self) -> RXOV_W

Bit 2 - Receiver Overrun interrupt flag. This flag applies only to slave mode (Master = 0). This flag is set when the beginning of a received character is detected while the receiver buffer is still in use. If this occurs, the receiver buffer contents are preserved, and the incoming data is lost. Data received by the SPI should be considered undefined if RxOv is set.

pub fn txur(&mut self) -> TXUR_W

Bit 3 - Transmitter Underrun interrupt flag. This flag applies only to slave mode (Master = 0). In this case, the transmitter must begin sending new data on the next input clock if the transmitter is idle. If that data is not available in the transmitter holding register at that point, there is no data to transmit and the TXUR flag is set. Data transmitted by the SPI should be considered undefined if TXUR is set.

pub fn ssa(&mut self) -> SSA_W

Bit 4 - Slave Select Assert. This flag is set whenever any slave select transitions from deasserted to asserted, in both master and slave modes. This allows determining when the SPI transmit/receive functions become busy, and allows waking up the device from reduced power modes when a slave mode access begins. This flag is cleared by software.

pub fn ssd(&mut self) -> SSD_W

Bit 5 - Slave Select Deassert. This flag is set whenever any asserted slave selects transition to deasserted, in both master and slave modes. This allows determining when the SPI transmit/receive functions become idle. This flag is cleared by software.

pub fn endtransfer(&mut self) -> ENDTRANSFER_W

Bit 7 - End Transfer control bit. Software can set this bit to force an end to the current transfer when the transmitter finishes any activity already in progress, as if the EOT flag had been set prior to the last transmission. This capability is included to support cases where it is not known when transmit data is written that it will be the end of a transfer. The bit is cleared when the transmitter becomes idle as the transfer comes to an end. Forcing an end of transfer in this manner causes any specified FRAME_DELAY and TRANSFER_DELAY to be inserted.
