Received Data Ready to be Read
Overrrun Error Detected
Idle Line Detected
In Halt mode, the SCI stops transmitting/receiving until Halt mode is exited.
Description
No effect on SCI.
SCI interrupts cause the device to exit from Wait mode.
SCI registers are frozen.
Interrupt Event
These events generate an interrupt if the corre-
sponding Enable Control Bit is set and the inter-
rupt mask in the CC register is reset (RIM instruc-
tion).
