2.1.8.1 GPIOs Available with Embedded Processing Option
The embedded processing option of TX62/TX82 provides a GPIO interface with 13 configu-
rable GPIO lines. Some GPIO lines are shared with other interfaces or functions, and are
shown in the following table with their default assignments being marked green.
After startup, the above mentioned alternative GPIO line assignments can be configured
through embedded applications (see [9]), or in the case of GPIO5 and GPIO8 also through AT
command. The configuration is non-volatile and available after module restart.
