22.6.2.4 Channel Setup

An event channel can select one event from a list of event generators. Depending on configuration, the selected event could be synchronized, resynchronized or asynchronously sent to the users. When synchronization or resynchronization is required, the channel includes an internal edge detector, allowing the Event System to generate internal events when rising, falling or both edges are detected on the selected event generator. An event channel is able to generate internal events for the specific software commands. All these configurations are available in the Channel register (CHANNEL).

To configure a channel, the Channel register must be written in a single 32-bit write. It is possible to read out the configuration of a channel by first selecting the channel by writing to CHANNEL.CHANNEL using a, 8-bit write, and then performing a read of the CHANNEL register.
