• Manufacturer: Renesas Technology

For operating modes after a reset, this LSI has not only a normal active mode but also three
power-down modes in which power consumption is significantly reduced. In addition, there is also
a module standby function which reduces power consumption by individually stopping on-chip
peripheral modules.

Active mode
The CPU and all on-chip peripheral modules are operable on the system clock. The system
clock frequency can be selected from osc, osc/8, osc/16, osc/32, and osc/64.
Sleep mode
The CPU halts. On-chip peripheral modules are operable on the system clock.
Standby mode
The CPU and all on-chip peripheral modules halt.
Subsleep mode
The CPU and all on-chip peripheral modules halt. I/O ports keep the same states as before the
transition.
Module standby function
Independent of the above modes, power consumption can be reduced by halting on-chip
peripheral modules that are not used in module units.
