Line Feed Motor Control

The SP/LF motor driver (Location 5A: MHM2025) drives the line feed motor in two-phase bipolar,
based on the phase changeover data output from the LSI.
The serial data from the LSI (02D:MSM79V035) is processed by a register contained in the SP/LF
motor driver to measure the overdrive time and to change the phase.
