Section 15 Serial Communication Interface with FIFO (SCIF)
Initial
Bit
Bit Name value R/W Description
4
RE
0
R/W Receive Enable
Enables or disables the SCIF serial receiver.
0:Receiver disabled*¹
1: Receiver enabled*²
Note: 1. Clearing RE to 0 does not affect the receive
flags (DR, ER, BRK, RDF, FER, PER, and
ORER). These flags retain their previous
values.
2. Serial reception starts when a start bit is
detected in asynchronous mode, or
synchronous clock input is detected in
synchronous mode. Select the receive format
in SCSMR and SCFCR and reset the receive
FIFO before setting RE to 1.
3
REIE
0
R Receive Error Interrupt Enable
Enables or disables the receive-error (ERI) interrupts
and break (BRI) interrupts. The setting of REIE bit is
valid only when RIE bit is set to 0.
0: Receive-error interrupt (ERI) and break interrupt
(BRI) requests are disabled*
1: Receive-error interrupt (ERI) and break interrupt
(BRI) requests are enabled
Note: * ERI or BRI interrupt requests can be cleared by
reading the ER, BR or ORER flag after it has
been set to 1, then clearing the flag to 0, or by
clearing RIE and REIE to 0. Even if RIE is set
to 0, when REIE is set to 1, ERI or BRI
interrupt requests are enabled.

0
R Reserved
This bit is always read as 0. The write value should
always be 0.
