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.
Serial Communications Interface Module (SCI)
1 = SCTE enabled to generate CPU interrupt
0 = SCTE not enabled to generate CPU interrupt
Enables the following 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
