TIE — Transmit Interrupt Enable Bit
This read/write bit enables SCI interrupt requests when the TDRE bit
becomes set. Reset clears 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 bit
becomes set. Reset clears the TCIE bit
1 = TC interrupt requests enabled
0 = TC interrupt requests disabled
RIE — Receive Interrupt Enable Bit
This read/write bit enables SCI interrupt requests when the RDRF bit
or the OR bit becomes set. Reset clears the RIE bit.
1 = RDRF interrupt requests enabled
0 = RDRF interrupt requests disabled
