BRK
0
R/(W)* Break Detection
Indicates that a break signal has been detected in
receive data.
0: No break signal received
[Clearing conditions]
• BRK is cleared to 0 when the chip is a power-on
reset
• BRK is cleared to 0 when software reads BRK
after it has been set to 1, then writes 0 to BRK
1: Break signal received*
[Setting condition]
BRK is set to 1 when data including a framing error is
received, and a framing error occurs with space 0 in
the subsequent receive data
Note: * When a break is detected, transfer of the
receive data (H'00) to SCFRDR stops after
detection. When the break ends and the
receive signal becomes mark 1, the transfer
of receive data resumes.

FER
0
R
Framing Error
Indicates a framing error in the data read from the
next receive FIFO data register (SCFRDR) in
asynchronous mode.
0: No receive framing error occurred in the next data
read from SCFRDR
[Clearing conditions]
• FER is cleared to 0 when the chip undergoes a
power-on reset
• FER is cleared to 0 when no framing error is
present in the next data read from SCFRDR
1: A receive framing error occurred in the next data
read from SCFRDR.
[Setting condition]
FER is set to 1 when a framing error is present in the
next data read from SCFRDR
