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 (04B: MSM79V035) is processed by a register contained in the SP/LF motor
driver to measure the overdrive time and to change the phase.
