5.2 Using 4CC GPIO Commands

TPS6598x Application Customization tool can be used to exercise the GPIO related 4CC commands and observe, develop system behavior before system controller implements the desired driver software. Figure 5-3 shows the commands list page of the tool that can be used to exercise the ‘GPxx’ 4CC commands.

For example, to set the GPIO7 to High:

  • First send ‘GPoe’ 4CC command as shown in Figure 5-4.
  • Then send ‘GPsh’ 4CC command as shown in Figure 5-5.
  • In the GPIO Status (0x72) it can be seen that GPIO7 has been set to High.
