When an enable input is high, the associated driver gets enabled. Motor drivers act as current amplifiers since they take a low-current control signal and provide a higher-current signal. Enable pins 1 and 9 (corresponding to the two motors) must be high for motors to start operating.

In its common mode of operation, two DC motors can be driven simultaneously, both in forward and reverse direction. If the image is beyond the maximum dimensions, it will be resized to fit within the maximum dimensions. Pictures larger than 75x75 pixels will be scaled down. The motor operations of two motors can be controlled by input logic at pins 2 & 7 and 10 & 15.
Logic 01 and 10 will rotate it in clockwise and anticlockwise directions, respectively. Similarly, when the enable input is low, that driver is disabled, and their outputs are off and in the high-impedance state.
