10.6.5 Low Power Modes
112/197
Mode
WAIT
HALT
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/re-
ceiving until Halt mode is exited.
Description
10.6.6 Interrupts
The SCI interrupt events are connected to the
same interrupt vector.
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).
