Functional Description
PWM Clock Generator
The PWM macrocell is primarily composed of a clock generator module and

Caution: Before using the PWM macrocell, the programmer must ensure that the PWM clock in
the Power Manager is enabled.
The PWM macrocell master clock, CLK_PWM, is divided in the clock generator module to pro-
vide different clocks available for all channels. Each channel can independently select one of the
