3.3 Analog Power Supply Voltage (JP: 15, 16, 21, 22)

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

provided internally or externally.

JP15, JP22 connect power supply voltages (AVcc and AVss)

JP16, JP21 connect reference voltages (AVRH1, AVRH2 to AVcc)

Jumper

JP15 (AVcc)

JP16 (AVRH2)

JP21 (AVRH1)

JP22 (AVss)

By default the resistor networks are not mounted on the board

By default, the A/D-converter supply and reference voltages are the same as the

microcontroller supply voltage.

Note:

If JP15, JP16 and J11 are open, the user has to supply an adequate analogue voltage

supply (AVcc and AVss) to the A/D-converter.

If JP16 is open, the resistors R22 and R27 define AVRH2.

If JP21 is open, the resistors R21 and R26 define AVRH1.

By default the resistor networks are not mounted on the board.
