Functional Description
PWM Clock Generator
CLK_PWM
GCLK
The PWM Controller is primarily composed of a clock generator module and 4 channels.
• The clock generator module provides 13 clocks. Its source clock is chosen according to the
• Each channel can independently choose one of the clock generator outputs.
• Each channel generates an output waveform with attributes that can be defined
CLKSEL bit in the Clock Register (CLK). It allows to select:
independently for each channel through the user interface registers.
CLKSEL
– CLK_PWM: the master clock (clock of the peripheral bus to which the PWM is
– GCLK: the generic clock (high frequency clock which is asynchronous to
connected)
