Flexray Cc Power Supply Voltage At Sk-91F467-Flexray - Fujitsu MB88121 SERIES User Manual

Jumper
JP15
JP16
JP18
Default: grey
*1
By default the resistor network (R10 and R13) is not assembled on the board
Note:
If JP15 or JP18 are open, the user has to supply an adequate analogue voltage supply (AVcc
and AVss) to the A/D-converter.
If JP16 is open, the potential divider comprising resistors R10 and R13 define AVRH.

3.4.3 FlexRay CC Power Supply Voltage at SK-91F467-FLEXRAY
