Value R/W Description
6 RIE 0 R/W Receive Interrupt Enable
Enables or disables the receive FIFO data full (RXI)
interrupts requested when the RDF flag or DR flag in
serial status register (SCFSR) is set to1, receive-error
(ERI) interrupts requested when the ER flag in SCFSR
is set to1, and break (BRI) interrupts requested when
the BRK flag in SCFSR or the ORER flag in line status
register (SCLSR) is set to1.
0: Receive FIFO data full interrupt (RXI), receive-error
interrupt (ERI), and break interrupt (BRI) requests
are disabled
1: Receive FIFO data full interrupt (RXI), receive-error
interrupt (ERI), and break interrupt (BRI) requests
are enabled*
Note: * RXI interrupt requests can be cleared by
reading the DR or RDF flag after it has
been set to 1, then clearing the flag to 0, or
by clearing RIE to 0. 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.
5 TE 0 R/W Transmit Enable
Enables or disables the serial transmitter.
0: Transmitter disabled
1: Transmitter enabled*
Note: * Serial transmission starts after writing of
transmit data into SCFTDR. Select the
transmit format in SCSMR and SCFCR and
reset the transmit FIFO before setting TE to
1.
