UART Break Error
Description
Value
No break condition has occurred
0
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).
data input was held Low for longer than a full-word transmission
time (defined as start, data, parity, and stop bits).
1
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.
