Texas Instruments SLAU081 manual Connectors, Reference Description Pin Function Designator Number

Connectors

If SW1-1 is set to the on position, user mode is selected. In this case the user has absolute control of the data and control signals for the ADC and DAC. With SW1-1 in the on position, the logic that generates the control for SAM is disabled and plays no active part in the process.

2.4 Connectors

In addition to jumpers and switches, the user also has access to various connectors. This section details the pinout of each connector.
