MOTOR Z EVENT FILTER REGISTER (MZFR)
Read/Write
Reset Value: 0000 1111 (0Fh)
Bits 7:4 = ZEF[3:0]: Z Event Filter bits
These bits select the number of valid consecutive
Z events (when the Z event is detected) needed to
generate the active event. Sampling is done at the
selected f
PWM frequency.

Bits 3:0 = ZWF[3:0]: Z Window Filter bits
These bits select the length of the blanking win-
dow activated at each D event. The filter blanks
the Z event detection until the end of the time win-
dow.
