UART ERROR STATUS REGISTER
There are four UART Rx error status registers including UERSTAT0, UERSTAT1, UERSTAT2 and UERSTAT3 in
the UART block.

Description
Initial
State
Break Detect
[3]
Set to 1 automatically to indicate that a break signal has been
received.
0 = No break receive
1 = Break receive (Interrupt is requested.)
0
Frame Error
[2]
Set to 1 automatically whenever a frame error occurs during
receive operation.
0 = No frame error during receive
1 = Frame error (Interrupt is requested.)
0
Parity Error
[1]
Set to 1 automatically whenever a parity error occurs during
receive operation.
0 = No parity error during receive
1 = Parity error (Interrupt is requested.)
0
Overrun Error
[0]
Set to 1 automatically whenever an overrun error occurs during
receive operation.
0 = No overrun error during receive
1 = Overrun error (Interrupt is requested.)
0
NOTE:
These bits (UERSATn[3:0]) are automatically cleared to 0 when the UART error status register is read.
