12.7.2 SCI Control Register 2
SCI control register 2 (SCC2):
SCTIE — SCI Transmit Interrupt Enable Bit
TCIE — Transmission Complete Interrupt Enable Bit

This read/write bit enables the SCTE bit to generate SCI transmitter CPU interrupt requests. Setting
the SCTIE bit in SCC3 enables the SCTE bit to generate CPU interrupt requests. Reset clears the
SCTIE bit.
This read/write bit enables the TC bit to generate SCI transmitter CPU interrupt requests. Reset clears
the TCIE bit.
1 = SCTE enabled to generate CPU interrupt
0 = SCTE not enabled to generate CPU interrupt
1 = TC enabled to generate CPU interrupt requests
0 = TC not enabled to generate CPU interrupt requests
Enables these CPU interrupt requests:
–

–
–
Enables the transmitter
Enables the receiver
Enables SCI wakeup
Transmits SCI break characters
Enables the SCTE bit to generate transmitter CPU interrupt requests
Enables the TC bit to generate transmitter CPU interrupt requests
Enables the SCRF bit to generate receiver CPU interrupt requests
Enables the IDLE bit to generate receiver CPU interrupt requests
