15.3.12 Line Status Register (SCLSR)
The CPU can always read or write to SCLSR, but cannot write 1 to the ORER flag. This flag can
be cleared to 0 only if it has first been read (after being set to 1).
Initial value:
Bit
15 to 1
0
Note:

Section 15 Serial Communication Interface with FIFO (SCIF)
Description
Reserved
These bits are always read as 0. The write value
should always be 0.
Indicates the occurrence of an overrun error.
0: Receiving is in progress or has ended normally*

ORER is cleared to 0 when the chip is a power-on
reset
ORER is cleared to 0 when 0 is written after 1 is
read from ORER.
ORER is set to 1 when the next serial receiving is
finished while the receive FIFO is full of 16-byte
receive data.

(SCFRDR) retains the data before an
overrun error has occurred, and the next
received data is discarded. When the
ORER bit is set to 1, the SCIF cannot
continue the next serial reception.
