Structure
The analog values are processed in parallel via two multiplexers and two analog/digital
converters with 12-bit resolution and the results are compared. This value is then made
available to the user program.
Additionally, test values are used by the existing digital/analog converters, converted back to
digital values, and then compared with the default value.
