This read/write bit enables the SCTE bit to generate SCI transmitter
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 requests
0 = SCTE not enabled to generate CPU interrupt requests
1 = TC enabled to generate CPU interrupt requests
0 = TC not enabled to generate CPU interrupt requests
Enables these CPU interrupt requests:
– Enables the SCTE bit to generate transmitter CPU interrupt
– Enables the TC bit to generate transmitter CPU interrupt
– Enables the SCRF bit to generate receiver CPU interrupt
– Enables the IDLE bit to generate receiver CPU interrupt
Enables the transmitter
Enables the receiver
Enables SCI wakeup
Transmits SCI break characters
