NOTE:
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.
RE — Receiver Enable Bit
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 10 or 11 logic 1s from the transmit shift register to the
PTB1/TxD pin. If software clears the TE bit, the transmitter completes
any transmission in progress before the PTB1/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.
Setting this read/write bit enables the receiver. Clearing the RE bit
disables the receiver but does not affect receiver interrupt flag bits.
Reset clears the RE bit.
1 = TC enabled to generate CPU interrupt requests
0 = TC not enabled to generate CPU interrupt requests
1 = SCRF enabled to generate CPU interrupt
0 = SCRF not enabled to generate CPU interrupt
1 = IDLE enabled to generate CPU interrupt requests
0 = IDLE not enabled to generate CPU interrupt requests
1 = Transmitter enabled
0 = Transmitter disabled
1 = Receiver enabled
0 = Receiver disabled
