Power Management
In Power Down Mode, both the CPU and the peripherals are stopped. The real time
clock and its selected oscillator may optionally be kept running. Power Down mode can
be terminated by a hardware reset only.
Note: All external bus actions are completed before a power saving mode is entered.
In addition the power management selects the current CPU frequency and controls
which peripherals are active.
During Slow Down Operation, the basic clock generation path is bypassed and the
CPU clock is generated via the programmable Slow Down Divider (SDD) from the
selected oscillator clock signal.
Peripheral Management disables and enables the on-chip peripheral modules
independently, reducing the amount of clocked circuitry (including the associated clock
drivers).
