Section 19 Serial Communication Interface with FIFO (SCIF)
19.3.12 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). SCLSR is initialized to H'0000
by a power-on reset.

These bits are always read as 0. The write value

Notes: 1. Clearing the RE bit to 0 in SCSCR does
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.

previous value.
hold the data before an overrun error is
occurred, and the next receive data is
extinguished. When ORER is set to 1,
SCIF cannot continue the next serial
receiving.
