You don't, not by the PIC anyway. There's a manual switch (not
shown in the diagram). The voltage across the sense resistor is
detected by the PIC and then sent to the LCD to show the state
of the motor wires. By inspection the operator knows whether to
use the manual switch

Sure. Use your 'kin imagination

You didn't count down instead of up did you ?
