0 = GPIO2 Manual Mode
GPIO2 is controlled manually via the standard AFG verbs
1 = GPIO Automatic Control Mode
GPIO2 is always an output and forced high when PS-Act of AFG is D1 or
D0. GPIO2 is forced low when PS-Act of AFG is D2, D3 or D4.

Priority
RW
00h
Assigns a priority setting for queued Unsolicited Responses. Nodes with
the lowest value have the highest priority, and so go to the front of the
Unsolicited Response queue. Nodes with the same value for priority are
queued on first-to-trigger basis.
00h = Highest priority
…
1Fh = Lowest priority.
