Functional Description
SAM3N
Interrupt Sources
PWM Clock Generator
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.
Table 32-3.
The PWM macrocell is primarily composed of a clock generator module and

Instance
– Clocked by the system clock, MCK, the clock generator module provides 13 clocks.
– Each channel can independently choose one of the clock generator outputs.
– Each channel generates an output waveform with attributes that can be defined
PWM
independently for each channel through the user interface registers.
