The dsPICPRO4 development system has an on-board 12-bit D/A converter MCP4921 used to per-
form digital-to-analog conversion. After conversion, the appropriate analog value appears on the
connector CN17. Similar to A/D converter unit, the dsPICPRO4 also enables reference voltage
selection for the operation of MCP4921 converter. The appropriate voltage is selected using the
jumper J16. The operation of this converter as well as its communication with the microcontroller
is enabled by switches 2, 3, 4 and 6 of the DIP switch SW4.
