32.6 Clocks
The EVSYS bus clock (CLK_EVSYS_APB) can be enabled and disabled in the Main Clock module (MCLK). The EVSYS APB BUS interface clocks, CLK_EVSYS_APB, are enabled by default on reset. (See MCLK).
Each EVSYS channel which can be configured as synchronous or resynchronized has a dedicated generic clock (GCLK_EVSYS_CHANNEL_n). These are used for event detection and propagation for each channel. These clocks must be configured and enabled in the generic clock controller before using the EVSYS. Refer to GCLK - Generic Clock Controller for details.
