Bits 15:8 – CHANNEL[7:0] 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[7:0]Channel Number
0x0No Channel Output Selected
0x1-0x08Channel n-1 selected
0x09-0xFFReserved

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.
