Description
Indicates that a break signal is detected in received
data in asynchronous mode.
0: No break signal is being received
[Clearing conditions]
•
•
1: A break signal is received *
[Setting conditions]
Data including a framing error is received

Note:
Framing Error
Indicates a framing error in the data read from the
receive FIFO data register (SCFRDR) in
asynchronous mode.
0: No framing error occurred in the data read from
[Clearing conditions]
•
•
1: A framing error occurred in the data read from
[Setting condition]

SCFRDR
SCFRDR
Power-on reset, manual reset
BRK is read as 1, then written to with 0
A framing error with space 0 occurs in the
subsequent received data
Power-on reset, manual reset
No framing error is present in the data read from
SCFRDR
A framing error is present in the data read from
SCFRDR
*
Serial Communication Interface with FIFO (SCIF)
When a break is detected, transfer of the
received data (H'00) to SCFRDR stops
after detection. When the break ends and
the receive signal becomes mark 1, the
transfer of the received data resumes.
