3.3 Analog Power Supply Voltage (JP: 3, 5, 7)
The power supply as well as the positive reference voltage for the A/D-converter can be
provided internally or externally.
connects analog power supply voltages (AVcc and AVss)
JP3, JP7
connects the analog reference voltage AVRH to AVcc
JP5
Jumper
JP3 (AVcc)
JP5 (AVRH)
JP7 (AVss)
*1
By default the resistor network (R4, R6) is not mounted on the board
Default: JP3, JP5 and JP7 are closed
By default, the A/D-converter supply and reference voltage is same as the microcontroller
supply voltage.
Note:
If JP3 and JP7 are open, the user has to supply an adequate analog voltage supply (AVcc
and AVss) to the A/D-converter.
If JP5 is open, the resistors R4 and R6 define AVRH.
By default the resistor network (R4, R6) is not mounted on the board.
