2 / 4 page 2 Current flow through the two outputs COIL+ and COIL- is controlled by the combined settings of ENABLE1, ENABLE2 and DIRECTION (Table 1). The outputs will be active only when ENABLE1 is low and ENABLE2 is high. When DIRECTION is high, current flows out of COIL+ and into COIL-. When DIRECTION is low, current flows out of COIL- and into COIL+. For any other combination of ENABLE settings, the outputs are off. Table 1.
