TCIE — Transmission Complete Interrupt Enable Bit
SCRIE — SCI Receive Interrupt Enable Bit
ILIE — Idle Line Interrupt Enable Bit
TE — Transmitter Enable Bit
Writing to the TE bit is not allowed when the enable SCI bit (ENSCI) is
clear. ENSCI is in SCI control register 1.
This read/write bit enables the TC bit to generate SCI transmitter CPU
interrupt requests. Reset clears the TCIE bit.
This read/write bit enables the SCRF bit to generate SCI receiver
CPU interrupt requests. Setting the SCRIE bit in SCC3 enables the
SCRF bit to generate CPU interrupt requests. Reset clears the SCRIE
bit.
This read/write bit enables the IDLE bit to generate SCI receiver CPU
interrupt requests. Reset clears the ILIE bit.
Setting this read/write bit begins the transmission by sending a
preamble of ten or eleven logic 1s from the transmit shift register to
the PTF5/TxD pin. If software clears the TE bit, the transmitter
completes any transmission in progress before the PTF5/TxD returns
to the idle condition (logic 1). Clearing and then setting TE during a
transmission queues an idle character to be sent after the character
currently being transmitted. Reset clears the TE bit.
