5.4.5 Low Power Modes
5.4.6 Interrupts
The SCI interrupt events are connected to the
same interrupt vector (see Interrupts chapter).
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).
Mode
Description
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.
