TCIE — Transmission Complete Interrupt Enable Bit
This read/write bit enables SCI interrupt requests when the TC flag
becomes set. Resets clear the TCIE bit.
1 = TC interrupt requests enabled
0 = TC interrupt requests disabled
RIE — Receiver Interrupt Enable Bit
This read/write bit enables SCI interrupt requests when the RDRF flag
or the OR flag becomes set. Resets clear the RIE bit.
1 = RDRF interrupt requests enabled
0 = RDRF interrupt requests disabled
ILIE — Idle Line Interrupt Enable Bit
This read/write bit enables SCI interrupt requests when the IDLE bit
becomes set. Resets clear the ILIE bit.
1 = IDLE interrupt requests enabled
0 = IDLE interrupt requests disabled
TE — Transmitter Enable Bit
Setting this read/write bit begins the transmission by sending a
preamble of 10 or 11 logic 1s from the transmit shift register to the
PD1/TDO pin. Resets clear the TE bit.
1 = Transmission enabled
0 = Transmission disabled
RE — Receiver Enable Bit
Setting this read/write bit enables the receiver. Clearing the RE bit
disables the receiver and receiver interrupts but does not affect the
receiver interrupt flags. Resets clear the RE bit.
1 = Receiver enabled
0 = Receiver disabled
