8.4.5.1 Command Controlled GPO
The UCD90320U device has 84 GPIO pins, all of which can be configured as Command Controlled GPOs. These GPOs are controlled by PMBus commands (GPIO_SELECT and GPIO_CONFIG) and can be used to control LEDs, enable switches, and so forth. Details on controlling a GPO using PMBus commands can be found in the UCD90320U Sequencer and System Health Controller PMBus Command Reference. The configuration window of Command Controlled GPO is under Pin Assignment tab. An example configuration window is shown in Figure 18.
