The comparator output is processed by a detector that automatically recognizes the D or Z
event, depending on the CPB or ZVD edge and level configuration bits as described in
Table
To avoid wrong detection of D and Z events, a blanking window filter is implemented for
spike filtering. In addition, by means of an event counter, software can filter several
consecutive events up to a programmed limit before generating the D or Z event internally.
This is shown in
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
Table
This window filter becomes active after both hardware and software C events.
The D event filter becomes active after the D window 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
forced to 1.
