Section 21 Serial Communication Interface with FIFO (SCIF)

Bit Bit
Name
Initial
Value R/W
Description
4 RE 0 R/W
Receive
Enable
Enables or disables the start of serial reception by the
SCIF.
Serial reception is started when a start bit is detected in
this state in asynchronous mode or a synchronization
clock is input while the RE bit is set to 1.
It should be noted that clearing the RE bit to 0 does not
affect the DR, ER, BRK, RDF, FER, PER flags in
SCFSR, and ORER flag in SCLSR, which retain their
states. Serial reception begins once the start bit is
detected in these states.
0: Reception disabled
1: Reception enabled
*
Note:
*
SCSMR and SCFCR settings must be made,
the reception format decided, and the receive
FIFO reset, before the RE bit is set to 1.
3
REIE
0
R/W
Receive Error Interrupt Enable
Enables or disables generation of receive-error
interrupt (ERI) and break interrupt (BRI) requests. The
REIE bit setting is valid only when the RIE bit is 0.
Receive-error interrupt (ERI) and break interrupt (BRI)
requests can be cleared by reading 1 from the ER,
BRK in SCFSR, or ORER flag in SCLSR, then clearing
the flag to 0, or by clearing the RIE and REIE bits to 0.
When REIE is set to 1, ERI and BRI interrupt requests
will be generated even if RIE is cleared to 0. In DMA
transfer, this setting is made if the interrupt controller is
to be notified of ERI and BRI interrupt requests.
0: Receive-error interrupt (ERI) and break interrupt
(BRI) requests disabled
1: Receive-error interrupt (ERI) and break interrupt
(BRI) requests enabled
2 — 0 R
Reserved
This bit is always read as 0. The write value should
always be 0.
