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

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.

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.
