TIE — Transmit Interrupt Enable Bit
This read/write bit enables SCI interrupt requests when the TDRE flag
becomes set. Resets clear the TIE bit.
1 = TDRE interrupt requests enabled
0 = TDRE interrupt requests disabled
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
