Description
Break Detect
Indicates that a receive data break signal has been detected
in asynchronous mode.
0: A break signal has not been received
[Clearing conditions]
•
•
1: A break signal has been received*
[Setting condition]
When data with a framing error is received, followed by the
space 0 level (low level) for at least one frame length
Note: 1.
Framing Error
Indicates a framing error in the data read from SCFRDR in
asynchronous mode.
0: There is no framing error in the receive data read from
[Clearing conditions]
•
•
1: There is a framing error in the receive data read from
[Setting condition]
When there is a framing error in SCFRDR read data
SCFRDR
SCFRDR
Power-on reset or manual reset
When 0 is written to BRK after reading BRK = 1
Power-on reset or manual reset
When there is no framing error in SCFRDR read data
When a break is detected, the receive data (H'00)
following detection is not transferred to SCFRDR.
When the break ends and the receive signal
returns to mark 1, receive data transfer is
resumed.
