Low power modes
Table 60.
Interrupts
The SCI interrupt events are connected to the same interrupt vector.
These events generate an interrupt if the corresponding Enable Control bit is set and the
interrupt mask in the CC register is reset (RIM instruction).

Interrupt event
No effect on SCI.
SCI interrupts cause the device to exit from Wait mode.
SCI registers are frozen.
In Halt mode, the SCI stops transmitting/receiving until Halt mode is exited.
