Step2::the servomotor stops when DIx(33)=1, meaning the DOG Pulse Rising edge
Step3::the servomotor rotates in Forward direction away from the DOG Pulse Rising edge
Step4::for the final step, the controller executes an P2P function commands the servomotor move to the
desired shift position (with respect to the DOG Pulse Rising edge. In the mean time, DOx(32)=1,
to indicate the end of the Home-Search function.
