Debug operation
Power Management
Interrupt Sources
The pins used for interfacing the PWM may be multiplexed with PIO lines. The programmer must
first program the PIO controller to assign the desired PWM pins to their peripheral function. If I/O
lines of the PWM are not used by the application, they can be used for other purposes by the
PIO controller.
Not all PWM outputs may be enabled. If an application requires only four channels, then only
four PIO lines will be assigned to PWM outputs.
The PWM clock is running during debug operation.
The PWM clock is generated by the Power Manager. Before using the PWM, the programmer
must ensure that the PWM clock is enabled in the Power Manager. 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 to the interrupt controller. Using the PWM interrupt requires
the interrupt controller to be programmed first.
