9.6.3 SCI Control Register 2
SCI control register 2 has the following functions:
Enables the SCI receiver and SCI receiver interrupts
Enables the SCI transmitter and SCI transmitter interrupts
Enables SCI receiver idle interrupts
Enables SCI transmission complete interrupts
Enables SCI wakeup
Transmits SCI break characters
TIE — Transmit Interrupt Enable
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
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
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
