(12) Output current timing chart under Ph inputs and I0, I1 output conditions.
Under output current waveforms show the current that a motor driver is going to control, so these do not show the
actual current waveforms. The waveform of the current when motor is driven becomes a corrupted-curved waveform
when the current changes due to the inductance of the motor.
