10.6.5 Low Power Modes

10.6.6 Interrupts

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.

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).
