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