Analog Power Supply Voltage (Jp: 11, 12, 13, 14) - Fujitsu SK-96380-120PMT User Manual

3.3 Analog Power Supply Voltage (JP: 11, 12, 13, 14)

The power supply as well as the positive reference voltage for the A/D-converter can be
provided internally or externally.
JP11, JP14 connects analog power supply voltages (AVcc and AVss)
JP12 connects the low pass filtered analog reference voltage AVRH to AVcc
JP13 connects the low pass filtered analog reference voltage AVRL to AVss

By default the resistor network (R16, R17, R20, R21) is not mounted on the board
Default: JP11, JP12, JP13, and JP14 are closed
By default, the A/D-converter supply and reference voltage is the same as the
microcontroller supply voltage.
Note:
If JP11 and JP14 are open, the user has to supply an adequate analog voltage supply (AVcc
and AVss) to the A/D-converter.
If JP12 and JP13 are open, the resistors R16, R17, R20, and R21 define AVRH and AVRL.
By default the resistor network (R16, R17, R20, and R21) is not mounted on the board.
