30.6.2.9 The Overrun Channel n Interrupt
The Overrun Channel n interrupt flag in the Interrupt Flag Status and Clear register (INTFLAG.OVRn) will be set, and the optional interrupt will be generated in the following cases:
- One or more event users on channel n is not ready when there is a new event.
- An event occurs when the previous event on channel m has not been handled by all event users connected to that channel.
The flag will only be set when using synchronous or resynchronized paths. In the case of asynchronous path, the INTFLAG.OVRn is always read as zero.
