We have different options for selecting on/off configuration say Control pin, Operation, Control and operation, please find the attachment. Where should we assign GPIO to control and operation in GUI, FYI we are using Fusion Digital power designer v2.0.89

    CONTROL pin is one of the PMBus pins. It is a fixed physical pin. OPERATION is a PMBus command.

    GPIOs can be defined as GPI and used for dependencies. But dependencies are only examined when a rail receives command to turn on/off. This command can be from CONTROL pin, OPERATION, or as a Fault Shutdown Slave of anther failed rail.
