Struct lpc81x_pac::usart0::stat::W

pub struct W { /* fields omitted */ }

Value to write to the register

Methods

impl W

pub fn reset_value() -> W

Reset value of the register

pub unsafe fn bits(&mut self, bits: u32) -> &mut Self

Writes raw bits to the register

pub fn rxrdy(&mut self) -> _RXRDYW

Bit 0 - Receiver Ready flag. When 1, indicates that data is available to be read from the receiver buffer. Cleared after a read of the RXDATA or RXDATASTAT registers.

pub fn rxidle(&mut self) -> _RXIDLEW

Bit 1 - Receiver Idle. When 0, indicates that the receiver is currently in the process of receiving data. When 1, indicates that the receiver is not currently in the process of receiving data.

pub fn txrdy(&mut self) -> _TXRDYW

Bit 2 - Transmitter Ready flag. When 1, this bit indicates that data may be written to the transmit buffer. Previous data may still be in the process of being transmitted. Cleared when data is written to TXDATA until the data is moved to the transmit shift register.

pub fn txidle(&mut self) -> _TXIDLEW

Bit 3 - Transmitter Idle. When 0, indicates that the transmitter is currently in the process of sending data.When 1, indicate that the transmitter is not currently in the process of sending data.

pub fn cts(&mut self) -> _CTSW

Bit 4 - This bit reflects the current state of the CTS signal, regardless of the setting of the CTSEN bit in the CFG register. This will be the value of the CTS input pin unless loopback mode is enabled.

pub fn deltacts(&mut self) -> _DELTACTSW

Bit 5 - This bit is set when a change in the state is detected for the CTS flag above. This bit is cleared by software.

pub fn txdisint(&mut self) -> _TXDISINTW

Bit 6 - Transmitter Disabled Interrupt flag. When 1, this bit indicates that the USART transmitter is fully idle after being disabled via the TXDIS in the CFG register (TXDIS = 1).

pub fn overrunint(&mut self) -> _OVERRUNINTW

Bit 8 - Overrun Error interrupt flag. This flag is set when a new character is received while the receiver buffer is still in use. If this occurs, the newly received character in the shift register is lost.

pub fn rxbrk(&mut self) -> _RXBRKW

Bit 10 - Received Break. This bit reflects the current state of the receiver break detection logic. It is set when the Un_RXD pin remains low for 16 bit times. Note that FRAMERRINT will also be set when this condition occurs because the stop bit(s) for the character would be missing. RXBRK is cleared when the Un_RXD pin goes high.

pub fn deltarxbrk(&mut self) -> _DELTARXBRKW

Bit 11 - This bit is set when a change in the state of receiver break detection occurs. Cleared by software.

pub fn start(&mut self) -> _STARTW

Bit 12 - This bit is set when a start is detected on the receiver input and subsequently confirmed by a mid-bit sample. Its purpose is primarily to allow wakeup from Power-down mode immediately when a start is detected. Cleared by software.

pub fn framerrint(&mut self) -> _FRAMERRINTW

Bit 13 - Framing Error interrupt flag. This flag is set when a character is received with a missing stop bit at the expected location. This could be an indication of a baud rate or configuration mismatch with the transmitting source.

pub fn parityerrint(&mut self) -> _PARITYERRINTW

Bit 14 - Parity Error interrupt flag. This flag is set when a parity error is detected in a received character, if parity is enabled via the Parity field in the CFG register.

pub fn rxnoiseint(&mut self) -> _RXNOISEINTW

Bit 15 - Received Noise interrupt flag. This bit is valid when there is a character to be read in the RXDATA register and reflects the status of that character. Three samples of received data are taken in order to determine the value of each received data bit, except in synchronous mode. This acts as a noise filter if one sample disagrees. The Noise bit is set when a received data bit contains one disagreeing sample. This could indicate line noise, a baud rate or character format mismatch, or loss of synchronization during data reception. RXNOISEINT is not updated during a received break.
