Description
UART Break Error
Value Description
1 A break condition has been detected, indicating that the receive
data input was held Low for longer than a full-word transmission
time (defined as start, data, parity, and stop bits).
0 No break condition has occurred
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 received data input
goes to a 1 (marking state), and the next valid start bit is received.
UART Parity Error
Value Description
1 The parity of the received data character does not match the
parity defined by bits 2 and 7 of the UARTLCRH register.
0 No parity error has occurred
In FIFO mode, this error is associated with the character at the top of
the FIFO.
UART Framing Error
Value Description
1 The received character does not have a valid stop bit (a valid
stop bit is 1).
0 No framing error has occurred
0x00
Data Transmitted or Received
Data that is to be transmitted via the UART is written to this field.
When read, this field contains the data that was received by the UART.
