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