SERIAL COMMUNICATIONS INTERFACE (Cont’d)
10.5.5 Low Power Modes
10.5.6 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).
Mode
Description
WAIT
No effect on SCI.
SCI interrupts cause the device to exit
from Wait mode.
HALT
SCI registers are frozen.
In Halt mode, the SCI stops transmit-
ting/receiving until Halt mode is exit-
ed.
