30.6.2.10 The Event Detected Channel n Interrupt
The Event Detected Channel n interrupt flag in the Interrupt Flag Status and Clear register (INTFLAG.EVDn) is set when an event coming from the event generator configured on channel n is detected.
The flag will only be set when using a synchronous or resynchronized path. In the case of asynchronous path, the INTFLAG.EVDn is always zero.
