24.4.3.3 Software Event

A software event can be initiated on a channel by writing the Channel n bit in the Software Event register (SWEVT.CHANNELn) to ‘1’, which will generate an event on channel n.

When using a software event on a channel with a resynchronized path, the CHSTATUS.CHBUSYn bit will not be set immediately. Wait three GCLK_EVSYS_CH_n clock cycles for the CHSTATUS.CHBUSYn bit to be set before issuing a new software event.
