12.6.1 Principle of Operation

The GCLK module is comprised of eight generic clock generators (generators) sourcing m generic clock multiplexers.

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 as input to one or more the generic clock multiplexers to provide a peripheral (GCLK_PERIPHERAL). A generic clock can act as the clock to one or several of peripherals.
