40.5.2 Power Management
The PWM is not continuously clocked. The programmer must first enable the PWM clock in the Power
Management Controller (PMC) before using the PWM. However, if the application does not require PWM
operations, the PWM clock can be stopped when not needed and be restarted later. In this case, the PWM will
resume its operations where it left off.
40.5.3 Interrupt Sources
The PWM interrupt line is connected on one of the internal sources of the Interrupt Controller. Using the PWM
interrupt requires the Interrupt Controller to be programmed first. Note that it is not recommended to use the PWM
interrupt line in edge sensitive mode.
40.5.4 Fault Inputs
The PWM has the FAULT inputs connected to the different modules. Please refer to the implementation of these
module within the product for detailed information about the fault generation procedure. The PWM receives faults
from PIO inputs, the PMC, the ADC controller, the Analog Comparator Controller and Timer/Counters.
