Move Home instruction initiates the corresponding PWM pulses and
Direction bit. In the example shown Figure 11, the MH instruction searches
in the forward (DIR is logic ‘0’) direction. Once the HM input is active (logic
‘0’), it toggles the Direction bit and reduces the speed of search, and
hence reverses the motion at a lower speed. This motion continues until
the HM input is inactive and the home operation is complete.

2.8. Testing Our Connections
Having connected all the necessary circuitry described in the above
sections, we can start testing our application by sending a couple of
