10: Pulse on SyncIn
11..14: not used
15: Quadrature A/B on encoder input <axis index>
2 Set preload value Value to load into encoder counter on preload event
3
Set preload function See table below

2 0: the preload event is triggered by an edge 1: it is triggered by the level
3 0: Preload function inactive, 1: active (in case of “preload once”, this bit will be automatically reset)
7 .. 4 0: Pulse on A0
1: Pulse on B0
2: Pulse on A1
…
