Auto-cutter driver circuit
Rotating the DC motor counterclockwise or clockwise causes the auto-cutter to execute a full cut
or a partial cut (one point left uncut). The driver IC (U6) has a full-bridge configuration and
controls motor rotation, clockwise and counterclockwise.
The position of the auto-cutter blade is detected by the signal connected to P67 of the CPU.
