Implementations

impl R

pub fn data(&self) -> DATA_R

Bits 0:7 - Receive (read) data character. Transmit (write) data character.

pub fn fe(&self) -> FE_R

Bit 8 - 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). In FIFO mode, this error is associated with the character at the top of the FIFO.

pub fn pe(&self) -> PE_R

Bit 9 - 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. In FIFO mode, this error is associated with the character at the top of the FIFO.

pub fn be(&self) -> BE_R

Bit 10 - 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). 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 oe(&self) -> OE_R

Bit 11 - Overrun error. This bit is set to 1 if data is received and the receive FIFO is already full. This is cleared to 0 once there is an empty space in the FIFO and a new character can be written to it.
