Enable/input mode (EN/IN)

When enable/input mode is selected, the six digital inputs are managed as described in Table 12, where x = 1, 2,

3 refers to the half-bridge driven, the digital input INHx/INx is simply indicated as INx and INLx/ENx as ENx. The

half-bridge x is enabled by setting ENx = 1, otherwise when ENx = 0 the half-bridge is left in high impedance.

When enabled, the half-bridge status is determined by the INx input: INx = 0 sets the state low (OUTx at GND),

INx = 1 sets the state high (OUTx = VM). The general EN pin is also reported in Table 12.
