Receive Status Register/Error Clear Register, UARTRSR/UARTECR

Implementations

impl Uartrsr

pub const fn oe(&self) -> bool

Overrun error. This bit is set to 1 if data is received and the FIFO is already full. This bit is cleared to 0 by a write to UARTECR. The FIFO contents remain valid because no more data is written when the FIFO is full, only the contents of the shift register are overwritten. The CPU must now read the data, to empty the FIFO.

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

Overrun error. This bit is set to 1 if data is received and the FIFO is already full. This bit is cleared to 0 by a write to UARTECR. The FIFO contents remain valid because no more data is written when the FIFO is full, only the contents of the shift register are overwritten. The CPU must now read the data, to empty the FIFO.

pub const fn be(&self) -> bool

Break error. This bit is set to 1 if a break condition was detected, indicating that the received data input was held LOW for longer than a full-word transmission time (defined as start, data, parity, and stop bits). This bit is cleared to 0 after a write to UARTECR. In FIFO mode, this error is associated with the character at the top of the FIFO. When a break occurs, only one 0 character is loaded into the FIFO. The next character is only enabled after the receive data input goes to a 1 (marking state) and the next valid start bit is received.

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

Break error. This bit is set to 1 if a break condition was detected, indicating that the received data input was held LOW for longer than a full-word transmission time (defined as start, data, parity, and stop bits). This bit is cleared to 0 after a write to UARTECR. In FIFO mode, this error is associated with the character at the top of the FIFO. When a break occurs, only one 0 character is loaded into the FIFO. The next character is only enabled after the receive data input goes to a 1 (marking state) and the next valid start bit is received.

pub const fn pe(&self) -> bool

Parity error. When set to 1, it indicates that the parity of the received data character does not match the parity that the EPS and SPS bits in the Line Control Register, UARTLCR_H. This bit is cleared to 0 by a write to UARTECR. In FIFO mode, this error is associated with the character at the top of the FIFO.

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

Parity error. When set to 1, it indicates that the parity of the received data character does not match the parity that the EPS and SPS bits in the Line Control Register, UARTLCR_H. This bit is cleared to 0 by a write to UARTECR. In FIFO mode, this error is associated with the character at the top of the FIFO.

pub const fn fe(&self) -> bool

Framing error. When set to 1, it indicates that the received character did not have a valid stop bit (a valid stop bit is 1). This bit is cleared to 0 by a write to UARTECR. In FIFO mode, this error is associated with the character at the top of the FIFO.

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

Framing error. When set to 1, it indicates that the received character did not have a valid stop bit (a valid stop bit is 1). This bit is cleared to 0 by a write to UARTECR. In FIFO mode, this error is associated with the character at the top of the FIFO.
