This read/write bit enables the SCTE bit to generate SCI transmitter
CPU interrupt requests. Setting the SCTIE bit in SCC3 enables SCTE
CPU interrupt requests. Reset clears the SCTIE bit.
1 = SCTE enabled to generate CPU interrupt
0 = SCTE not enabled to generate CPU interrupt
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 wake up
Transmits SCI break characters
