These parameters are characterized but not tested in manufacturing.
Alignment of Index Pulses to QEA and QEB is shown for Position Counter reset timing only. Shown for
forward direction only (QEA leads QEB). Same timing applies for reverse direction (QEA lags QEB) but
Index Pulse recognition occurs on falling edge.
