15.6.1 Principle of Operation

The GCLK module is comprised of twelve Generic Clock Generators (Generators) sourcing up to 46 Peripheral Channels and the Main Clock signal GCLK_MAIN.

A clock source selected as input to a Generator can either be used directly or it can be prescaled in the Generator. A generator output is used by one or more Peripheral Channels to provide a peripheral generic clock signal (GCLK_PERIPH[m]) to the peripherals.
