15.6.1 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.
