Description
UART Break Error
Value Description
0 No break condition has occurred
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).
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
0 No parity error has occurred
1 The parity of the received data character does not match the
parity defined by bits 2 and 7 of the UARTLCRH register.
In FIFO mode, this error is associated with the character at the top of
the FIFO.
UART Framing Error
Value Description
0 No framing error has occurred
1 The received character does not have a valid stop bit (a valid
stop bit is 1).
0x00
Data Transmitted or Received
Data that is to be transmitted via the UART is written to this field.
