Power Management

Interrupt Sources

Fault Inputs

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.

The PWM interrupt line is connected on one of the internal sources of the Nested Vectored Inter-

rupt Controller (NVIC). Using the PWM interrupt requires the NVIC to be programmed first.

The PWM has the FAULT inputs connected to the different modules. Please refer to the imple-

mentation 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
