6.1.6.1 Encoder Mode
The Behavior of A/B Phase 4X Quadrant Counter
The figure below shows Encoder Mode counter behavior. Ch0_A and Ch0_B are sin-
gle-ended signals from the incremental encoder, if the "A" pulse is rising 90° ahead of
the "B" pulse, the counter value increases; if the "B" pulse is rising ahead of the "A",
the counter value decreases.
Blue are 0x6000, 0x7000, 0x8000 parameters.
Red are external signals.
n=0~1 for Ch0~1
The counter value and A, B phase status can be read at below Index:
