LINSCI

™ SERIAL COMMUNICATION INTERFACE (SCI Mode) (cont’d)

11.5.6 Low Power Modes

11.5.7 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).

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 transmitting/re-

ceiving until Halt mode is exited.
