3.3 Analog Power Supply Voltage (JP: 11, 13, 15)

The power supply as well as the positive reference voltage for the A/D-converter can be

provided internally or externally.

JP11, JP15 connects analog power supply voltages (AVcc and AVss)

JP13

JP11 (AVcc)

JP13 (AVRH)

JP15 (AVss)

Default: JP11, JP13 and JP15 are closed

By default, the A/D-converter supply and reference voltage is same as the microcontroller

supply voltage.

Note:

If JP11 and JP15 are open, the user has to supply an adequate analog voltage supply (AVcc

and AVss) to the A/D-converter.

If JP13 is open, the resistors R11 and R23 define AVRH.

By default the resistors R11 and R23 are not mounted on the board.
