SAM4S Series [Preliminary]
37.5.2 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.
37.5.3 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.
37.5.4 Fault Inputs
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, Analog Comparator
Controller and Timer/Counters
