Flag Register, UARTFR

Implementations

impl Uartfr

pub const fn ri(&self) -> bool

Ring indicator. This bit is the complement of the UART ring indicator, nUARTRI, modem status input. That is, the bit is 1 when nUARTRI is LOW.

pub fn set_ri(&mut self, val: bool)

Ring indicator. This bit is the complement of the UART ring indicator, nUARTRI, modem status input. That is, the bit is 1 when nUARTRI is LOW.

pub const fn txfe(&self) -> bool

Transmit FIFO empty. The meaning of this bit depends on the state of the FEN bit in the Line Control Register, UARTLCR_H. If the FIFO is disabled, this bit is set when the transmit holding register is empty. If the FIFO is enabled, the TXFE bit is set when the transmit FIFO is empty. This bit does not indicate if there is data in the transmit shift register.

pub fn set_txfe(&mut self, val: bool)

Transmit FIFO empty. The meaning of this bit depends on the state of the FEN bit in the Line Control Register, UARTLCR_H. If the FIFO is disabled, this bit is set when the transmit holding register is empty. If the FIFO is enabled, the TXFE bit is set when the transmit FIFO is empty. This bit does not indicate if there is data in the transmit shift register.

pub const fn rxff(&self) -> bool

Receive FIFO full. The meaning of this bit depends on the state of the FEN bit in the UARTLCR_H Register. If the FIFO is disabled, this bit is set when the receive holding register is full. If the FIFO is enabled, the RXFF bit is set when the receive FIFO is full.

pub fn set_rxff(&mut self, val: bool)

Receive FIFO full. The meaning of this bit depends on the state of the FEN bit in the UARTLCR_H Register. If the FIFO is disabled, this bit is set when the receive holding register is full. If the FIFO is enabled, the RXFF bit is set when the receive FIFO is full.

pub const fn txff(&self) -> bool

Transmit FIFO full. The meaning of this bit depends on the state of the FEN bit in the UARTLCR_H Register. If the FIFO is disabled, this bit is set when the transmit holding register is full. If the FIFO is enabled, the TXFF bit is set when the transmit FIFO is full.

pub fn set_txff(&mut self, val: bool)

Transmit FIFO full. The meaning of this bit depends on the state of the FEN bit in the UARTLCR_H Register. If the FIFO is disabled, this bit is set when the transmit holding register is full. If the FIFO is enabled, the TXFF bit is set when the transmit FIFO is full.

pub const fn rxfe(&self) -> bool

Receive FIFO empty. The meaning of this bit depends on the state of the FEN bit in the UARTLCR_H Register. If the FIFO is disabled, this bit is set when the receive holding register is empty. If the FIFO is enabled, the RXFE bit is set when the receive FIFO is empty.

pub fn set_rxfe(&mut self, val: bool)

Receive FIFO empty. The meaning of this bit depends on the state of the FEN bit in the UARTLCR_H Register. If the FIFO is disabled, this bit is set when the receive holding register is empty. If the FIFO is enabled, the RXFE bit is set when the receive FIFO is empty.

pub const fn busy(&self) -> bool

UART busy. If this bit is set to 1, the UART is busy transmitting data. This bit remains set until the complete byte, including all the stop bits, has been sent from the shift register. This bit is set as soon as the transmit FIFO becomes non-empty, regardless of whether the UART is enabled or not.

pub fn set_busy(&mut self, val: bool)

UART busy. If this bit is set to 1, the UART is busy transmitting data. This bit remains set until the complete byte, including all the stop bits, has been sent from the shift register. This bit is set as soon as the transmit FIFO becomes non-empty, regardless of whether the UART is enabled or not.

pub const fn dcd(&self) -> bool

Data carrier detect. This bit is the complement of the UART data carrier detect, nUARTDCD, modem status input. That is, the bit is 1 when nUARTDCD is LOW.

pub fn set_dcd(&mut self, val: bool)

Data carrier detect. This bit is the complement of the UART data carrier detect, nUARTDCD, modem status input. That is, the bit is 1 when nUARTDCD is LOW.

pub const fn dsr(&self) -> bool

Data set ready. This bit is the complement of the UART data set ready, nUARTDSR, modem status input. That is, the bit is 1 when nUARTDSR is LOW.

pub fn set_dsr(&mut self, val: bool)

Data set ready. This bit is the complement of the UART data set ready, nUARTDSR, modem status input. That is, the bit is 1 when nUARTDSR is LOW.

pub const fn cts(&self) -> bool

Clear to send. This bit is the complement of the UART clear to send, nUARTCTS, modem status input. That is, the bit is 1 when nUARTCTS is LOW.

pub fn set_cts(&mut self, val: bool)

Clear to send. This bit is the complement of the UART clear to send, nUARTCTS, modem status input. That is, the bit is 1 when nUARTCTS is LOW.
