Description

BRK

R/(W)*

Break Detect

In asynchronous mode, indicates that a receive

data break signal has been detected or not.

0: A break signal has not been received

[Clearing conditions]

• Power-on reset or manual reset

• When 0 is written to BRK after reading BRK = 1

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: * 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.

FER

Framing Error

In asynchronous mode, indicates that there is a

framing error or not in the data read from SCFRDR.

0: There is no framing error in the receive data read

from SCFRDR

[Clearing conditions]

• Power-on reset or manual reset

• When there is no framing error in SCFRDR read

data

1: There is a framing error in the receive data read

from SCFRDR

[Setting condition]

When there is a framing error in SCFRDR read data
