Description
Receive Enable
Enables or disables the SCIF serial receiver.
0:Receiver disabled*
1: Receiver enabled*
Notes: 1. Clearing RE to 0 does not affect the receive
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
1: Receive-error interrupt (ERI) and break interrupt
Note: * ERI or BRI interrupt requests can be cleared

(BRI) requests are disabled*
(BRI) requests are enabled
2. Serial reception starts when a start bit is
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.

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.
