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
connects the analog reference voltage AVRH to AVcc
Jumper
JP11 (AVcc)
JP13 (AVRH)
JP15 (AVss)
*1
By default the resistor network (R11, R23) is not mounted on the board
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 resistor network (R11, R23) is not mounted on the board.
