Getting Started
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.
