38.5.2 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.
In the PWM description, Master Clock (MCK) is the clock of the peripheral bus to which the PWM is connected.
38.5.3 Interrupt Sources
The PWM interrupt line is connected on one of the internal sources of the Nested Vectored Interrupt Controller
(NVIC). Using the PWM interrupt requires the NVIC to be programmed first.
38.5.4 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, PMC, ADC controller, and Timer/Counters
