10.6.6.4 Z Event Detection
In sensorless mode, the Z window filter becomes
active after each D event. It blanks out the Z event
during the time window defined by the ZWF[3:0]
bits in the MZFR register (see
value is 200µs. This Window Filter becomes active
after both hardware and software D events.
The Z Event Filter becomes active after the Z Win-
dow Filter. It counts the number of consecutive Z
events up to a limit defined by the ZEF[3:0] bits in
the MZFR register. The reset value is 1. The Z bit
is set when the counter limit is reached.
Sampling is done at a selectable frequency

The Z event filter is active only for a hardware Z
event (Z
