Motor driver, internal PWM current control operation mode
PWM current control is made, so that the peak current flowing through the motor coil with PWM = “H” does not exceed
the current level swt with VREF pins (pin 15 (Ach) and pin 13 (Bch)).
< MDINT = “L” (FAST mode) >
< MDINT = “H” (SLOW mode) >
