7.1.2 Modes of Operation
Be careful when using this module in some operating modes.
To accommodate this situation, PWM outputs are placed in their inactive states in stop
mode, and they can optionally be placed in inactive states in wait and debug (EOnCE)
modes. PWM outputs are reactivated (assuming they were active beforehand) when these
modes are exited.
7.1.3 Block Diagram
The following figure is a block diagram of the PWM.

Wait
Some applications (such as three-phase AC motors) require
regular software updates for proper operation. Failure to
provide regular software updates could result in destroying the
hardware setup.
Table 7-2. Modes When PWM Operation is Restricted
PWM outputs are inactive.
PWM outputs are driven or inactive as a function of CTRL2[WAITEN].
CPU and peripheral clocks continue to run, but the CPU may stall for periods of time. PWM outputs
are driven or inactive as a function of CTRL2[DBGEN].
