Description

RIE

R/W

Receive Interrupt Enable

Enables or disables generation of a receive-data-full

interrupt (RXI) request when the RDF flag or DR flag

in SCFSR is set to 1, receive-error interrupt (ERI)

request when the ER flag in SCFSR is set to 1, or

break-interrupt (BRI) request when the BRK flag in

SCFSR or the ORER flag in SCLSR is set to 1.

0: Receive-data-full interrupt (RXI) request, receive-

error interrupt (ERI) request, and break-interrupt

(BRI) request disabled*

1: Receive-data-full interrupt (RXI) request, receive-

error interrupt (ERI) request, and break-interrupt

(BRI) request enabled

Note: *

An RXI request can be cleared by reading 1

from the RDF flag or DR flag, then clearing

the flag to 0, or by clearing the RIE bit to 0.

The ERI and BRI requests can be cleared

by reading 1 from the ER, BRK, or ORER

flag, then clearing the flag to 0, or clearing

the RIE and REIE bits to 0.

R/W

Transmit Enable

Enables or disables the start of serial transmission by

the SCIF.

0: Transmission disabled

1: Transmission enabled*

Note: *

SCSMR and SCFCR settings must be

made, the transmit format decided, and the

transmit FIFO reset, before the TE bit is set

to 1.
