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

function, and transition function to power-down mode.

• Multi-clock function

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

clock, and external bus clock.

• Module stop function

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

• Transition function to power-down mode

Transition to a power-down mode is possible to stop the CPU, all the on-chip peripheral

modules, and oscillator.

• Three power-down modes

All-module-clock-stop mode

Software standby mode

Table 19.1 shows conditions for making a transition to a power-down mode, states of the CPU and

peripheral modules, and clearing method for each mode. After the reset state, since this LSI

operates in normal program execution state, the modules, other than the DMAC are stopped.
