3-3. Mecha drive
Each reel motor is linked to the CPU with two input signals (FWD IN, REW IN) and one output signal
(MTR OUT). With the input signals, the CPU judges the motor status (run or stop).
With the output signal, the CPU controls the motor rotation.
The control ports (IC6 CPU) for reel motor are as listed below.
