Receiver Interrupts
23-sci_d
MOTOROLA
NOTE:
The following sources can generate CPU interrupt requests from the SCI
receiver:
When receiver DMA service requests are enabled (DMARE = 1), then
receiver CPU interrupt requests are disabled.

For More Information On This Product,
SCI receiver full (SCRF) — The SCRF bit in SCS1 indicates that
the receive shift register has transferred a character to the SCDR.
SCRF can generate a receiver CPU interrupt request or a receiver
DMA service request. Setting the SCI receive interrupt enable bit,
SCRIE, in SCC2 enables the SCRF bit to generate receiver CPU
interrupts. Setting both the SCRIE bit and the DMA receive enable
bit, DMARE, in SCC3 enables receiver DMA service requests and
disables receiver CPU interrupt requests.
Idle input (IDLE) — The IDLE bit in SCS1 indicates that 10 or 11
consecutive logic 1s shifted in from the RxD pin. The idle line
interrupt enable bit, ILIE, in SCC2 enables the IDLE bit to generate
CPU interrupt requests.
