SERIAL COMMUNICATIONS INTERFACE (Cont’d)
7.7.5 Low Power Modes
7.7.6 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).

Description
WAIT
No effect on SCI.
