Functional Description
PWM Clock Generator
The PWM macrocell is primarily composed of a clock generator module and 7 channels.
Figure 32-2. Functional View of the Clock Generator Block Diagram
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, MCK, is divided in the clock generator module to provide dif-
ferent clocks available for all channels. Each channel can independently select one of the
divided clocks.
– 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
independently for each channel through the user interface registers.
