3.8.23 Automation Connector Header J59

This header is used for automating tests on the development platform. Such tests include powering on and off
and managing automated software downloads on the board. If automation is not required, user can access
free GPIO pins from this header. Table 3.8.23-1 below outlines the pins that are available via header J59.
Please refer to carrier and SOM schematics for details on where signals are connected to.
