TCIE — Transmission Complete Interrupt Enable Bit
RIE — Receive Interrupt Enable Bit
ILIE — Idle Line Interrupt Enable Bit
TE — Transmit Enable Bit
RE — Receive Enable Bit
This read/write bit enables SCI interrupt requests when the TC bit
becomes set. Reset clears the TCIE bit.
This read/write bit enables SCI interrupt requests when the RDRF bit
or the OR bit becomes set. Reset clears the RIE bit.
This read/write bit enables SCI interrupt requests when the IDLE bit
becomes set. Reset clears the ILIE 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. Reset clears the TE 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. Reset clears the RE bit.
