Module Standby Mode

5.9.1

Setting Module Standby Mode

Module standby mode is set for individual peripheral functions. All the on-chip peripheral

modules can be placed in module standby mode. When a module enters module standby mode,

the system clock supply to the module is stopped and operation of the module halts. This state is

identical to standby mode.

Module standby mode is set for a particular module by setting the corresponding bit to 0 in clock

stop register 1 (CKSTPR1) or clock stop register 2 (CKSTPR2). (See table 5.5.)

5.9.2

Clearing Module Standby Mode

Module standby mode is cleared for a particular module by setting the corresponding bit to 1 in

clock stop register 1 (CKSTPR1) or clock stop register 2 (CKSTPR2). (See table 5.5.)

Following a reset, clock stop register 1 (CKSTPR1) and clock stop register 2 (CKSTPR2) are both

initialized to H'FF.
