Analog Power Supply Voltage (Jp: 9, 8, 10) - Fujitsu MB91460 SERIES User Manual

3.3 Analog Power Supply Voltage (JP: 9, 8, 10)

The power supply as well as the positive reference voltage for the A/D-converter can be
provided internally or externally.
JP3, JP7 connects analog power supply voltages (AVcc and AVss)
JP5 connects the analog reference voltage AVRH to AVcc
Jumper
JP9 (AVcc)
JP10 (AVRH)
JP8 (AVss)
*1
By default the resistor network (R4, R6) is not mounted on the board
Default: JP9, JP10 and JP8 are closed
By default, the A/D-converter supply and reference voltage is connected to VCC3V3 (3.3V)
Note:
If JP8 and JP9 are open, the user has to supply an adequate analog voltage supply (AVcc
and AVss) to the A/D-converter.
If JP10 is open, the resistors R4 and R6 define AVRH.
By default the resistor network (R4, R6) is not mounted on the board.
