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.
This read/write bit enables the SCRF bit to generate SCI receiver CPU interrupt requests. Reset clears
the SCRIE 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
1 = SCRF enabled to generate CPU interrupt
0 = SCRF not enabled to generate CPU interrupt
Enables the following CPU interrupt requests:
