7.4.7 GPO Control

The GPIOs when configured as outputs can be controlled by PMBus commands or through logic defined in internal Boolean function blocks. Controlling GPOs by PMBus commands (GPIO_SELECT and GPIO_CONFIG) can be used to have control over LEDs, enable switches, etc. with the use of an I2C interface. See the UCD90xxx Sequencer and System Health Controller PMBus Command Reference for details on controlling a GPO using PMBus commands.
