Bits 12:8 – CHANNEL[4:0] Channel Event Selection
These bits are used to select the channel to connect to the event user.
Note that to select channel n, the value (n+1) must be written to the USER.CHANNEL bit group.
| CHANNEL[4:0] | Channel Number | 
|---|---|
| 0x0 | No Channel Output Selected | 
| 0x1-0xC | Channel n-1 selected | 
| 0xD-0xFF | Reserved | 
Bits 7:0 – USER[7:0] User Multiplexer Selection
These bits select the event user to be configured with a channel, or the event user to read the channel value from.
