Full Cutter Motor Driver Circuit and Media Feed Motor Driver Circuit

(1) Full cutter motor driver circuit
The circuit drives the DC motor to cut a medium as described in subsection 2.1.4
"Automatic Tape Full Cutter Mechanism".
When the CPU receives cut request from the key or software, it confirms that the
top cover ASSY is closed, and turns VHON (91 pin) High. Then the CPU controls
C_DCF (114 pin) and C_DCR (115 pin) to drive the cutter motor.
(2) Media feed motor driver circuit
When the CPU receives feed request from the key, it confirms that the top cover
ASSY is closed, and turns VHON (91 pin) High. Then the CPU controls SIN1 (27
pin) through SIN6 (20 pin) to drive the media feed motor.
