Section 23 Power-Down Modes

This LSI has power consumption reduction functions, such as multi-clock function, module stop

function, and transition function to power-down mode.

23.1

Features

• Multi-clock function

• The frequency division ratio is settable independently for the system clock, peripheral module

clock, and external bus clock.

• The system clock, peripheral module clock, and external bus clock can be uniformly set to the

32.768 kHz subclock.

• Module stop function

The functions for each peripheral modules can be stopped to make a transition to a power-

down mode.

• Transition function to power-down mode

Transition to a power-down mode is possible to stop the CPU, peripheral modules, and

oscillator.

• Four power-down modes

Sleep mode

All-module-clock-stop mode

Software standby mode

Hardware standby mode
