Analogue Power Supply Voltage (Jp: 11, 13, 15) - Fujitsu SK-96620_350-64PMC(1) User Manual

4.7 Analogue 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 low pass filtered analog reference voltage AVRH to AVcc
Jumper
JP11 (AVcc)
JP13 (AVRH)
JP15 (AVss)
Rule 5: By default, the A/D-converter supply and reference voltage is the same as
the microcontroller supply voltage.
Note:
If JP11 and J15 are open, the user has to supply an adequate analogue 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 and R23) is not mounted on the board.
