Table 3-9: FlexRay CC Supply
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 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.
