This LSI has power consumption reduction functions, such as multi-clock function, module stop
function, and transition function to power-down mode.
20.1
• Multi-clock function
• Module stop function
• Transition function to power-down mode
• Four power-down modes
Table 20.1 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 and DTC are
stopped.
The frequency division ratio is settable independently for the system clock, peripheral module
clock, and external bus clock.
The functions for each peripheral modules can be stopped to make a transition to a power-
down state.
Transition to a power-down mode is possible to stop the CPU, peripheral modules, and
oscillator.
