When off, a high-impedance state. • The ENA goes to the standby state with a low-level input, and to the operating state with a high-level input. • The control input switches the forward/reverse mode. • The comparator and PIPR can independently control the terminal CONT. It is irrelevant to the state of IN4 from IN1.
