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
Table
and software D events.
The Z event filter becomes active after the Z window 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 (f
The Z event filter is active only for a hardware Z event (Z
forced to 1. Z event filter is also active in sensor mode.
