Analogue Power Supply Voltage - Fujitsu SK-91465X-100PMC User Manual

3.3 Analogue Power Supply Voltage

The power supply as well as the positive reference voltage for the A/D-converter can be
provided internally or externally.
JP2, JP8 connects analogue power supply voltages (AVcc and AVss)
JP3 connects the analogue reference voltage AVRH to AVcc
Jumper
JP2 (AVcc)
JP3 (AVRH)
JP7 (AVss)
Default: grey

*1
By default the resistor network (R8, R11) is not mounted on the board
By default, the A/D-converter supply and reference voltage is same as the microcontroller
supply voltage.

Setting Description
Closed AVcc is connected to Vcc
Open AVcc is disconnected from Vcc
Closed AVRH is connected to AVcc
Open AVRH defined by resistor network
Closed AVss is connected to GND
Open AVss is disconnected from GND
Note:
If JP2 and JP7 are open, the user has to supply an
adequate analogue voltage supply (AVcc and AVss) to
the A/D-converter.
If JP3 is open, the resistors R8 and R11 define AVRH.
By default the resistor network (R8, R11) is not
mounted on the board.
