Section 14 Serial Communication Interface with FIFO (SCIF)
Rev. 2.00 Mar 09, 2006 page 568 of 906
REJ09B0292-0200
Bit 6—Receive Interrupt Enable (RIE): Enables or disables generation of a receive-FIFO-data-full
interrupt (RXI) request and receive-error interrupt (ERI) request when, after serial receive data is
transferred from the receive shift register (SCRSR) to the receive FIFO data register (SCFRDR),
the number of data bytes in SCFRDR reaches or exceeds the receive trigger set number, and the
RDF flag is set to 1 in SC1SSR.
Bit 6: RIE
Description
0
Receive-FIFO-data-full interrupt (RXI) request, receive-error interrupt (ERI)
request, and break interrupt (BRI) request disabled
*
(Initial value)
1
Receive-FIFO-data-full interrupt (RXI) request, receive-error interrupt (ERI)
request, and break interrupt (BRI) request enabled
Note:
*
RXI, ERI, and BRI interrupt requests can be cleared by reading 1 from the RDF or DR flag,
the FER, PER, ORER, or ER flag, or the BRK flag, then clearing the flag to 0, or by clearing
the RIE bit to 0. With the RDF flag, read receive data from SCFRDR until the number of
receive data bytes is less than the receive trigger set number, then read 1 from the RDF
flag and clear it to 0.
Bit 5—Transmit Enable (TE): Enables or disables the start of serial transmission by the SCIF.
Bit 5: TE
Description
0
Transmission disabled
*
1
(Initial
value)
1
Transmission enabled
*
2
Notes: 1. The TDRE flag in SC1SSR is fixed at 1.
2. Serial transmission is started when transmit data is written to SCFTDR in this state.
Serial mode register (SCSMR) and FIFO control register (SCFCR) settings must be
made, the transmission format decided, and the transmit FIFO reset, before the TE bit
is set to 1.
Bit 4—Receive Enable (RE): Enables or disables the start of serial reception by the SCIF.
Bit 4: RE
Description
0
Reception disabled
*
1
(Initial value)
1
Reception enabled
*
2
Notes: 1. Clearing the RE bit to 0 does not affect the RDF, DR, FER, PER, ORER, ER, and BRK
flags, which retain their states.
2. Serial reception is started in this state when a start bit is detected in asynchronous
mode or serial clock input is detected in synchronous mode.
SCSMR settings must be made to decide the reception format before setting the RE bit
to 1.
