Bits 27,26,25,24,15,14,13,12,11,10,9,8 – EVDn Channel n Event Detection [n=11..0]
This flag is set on the next CLK_EVSYS_APB cycle when an event is being propagated through the
channel, and an interrupt request will be generated if INTENCLR/SET.EVDn is one.
When the event channel path is asynchronous, the EVDn interrupt flag will not be set.
Writing a zero to this bit has no effect.
Writing a one to this bit will clear the Event Detected Channel n interrupt flag.
Bits 19,18,17,16,7,6,5,4,3,2,1,0 – OVRn Channel n Overrun [n=11..0]
This flag is set on the next CLK_EVSYS cycle after an overrun channel condition occurs, and an interrupt
request will be generated if INTENCLR/SET.OVRn is one.
When the event channel path is asynchronous, the OVRn interrupt flag will not be set.
Writing a zero to this bit has no effect.
Writing a one to this bit will clear the Overrun Channel n interrupt flag.
