Wait mode is intended to be used to stop only the CPU and memory
clocks until a wakeup event is detected. In this mode, peripherals may
be programmed to continue operating and can generate interrupts,
which cause the CPU to exit from wait mode.
Doze mode affects the CPU in the same manner as wait mode, except
that each peripheral defines individual operational characteristics in
doze mode. Peripherals which continue to run and have the capability of
producing interrupts may cause the CPU to exit the doze mode and
return to run mode. Peripherals which are stopped will restart operation
on exit from doze mode as defined for each peripheral.
Stop mode affects the CPU in the same manner as the wait and doze
modes, except that all clocks to the system are stopped and the
peripherals cease operation.
Stop mode must be entered in a controlled manner to ensure that any
current operation is properly terminated. When exiting stop mode, most
peripherals retain their pre-stop status and resume operation.
The following subsections specify the operation of each module while in
and when exiting low-power modes.
Most peripherals may be disabled by software in order to cease internal
clock generation and remain in a static state. Each peripheral has its own
specific disabling sequence (refer to each peripheral description for
further details). A peripheral may be disabled at any time and will remain
disabled during any low-power mode of operation.
