LINSCI™ SERIAL COMMUNICATION INTERFACE (SCI Mode) (cont’d)
10.5.6 Low Power Modes

Mode
Wait
Halt
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/re-
ceiving until Halt mode is exited.
10.5.7 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).
