AT90CAN128 is the AGND pin electrically separate from GND?
On page 4 of the datasheet there is a diagram of the processor, at the ADC section the label AGND is used. On page 5 showing the chip pinout PIN63 is labelled as GND (same as pins 53 and 22).
Are these three pins connected on the die? I'm looking at a circuit design which assumes PIN63 is separate, the PCB uses a dedicated ground return for this pin and decoupling components for AVCC and AREF.
All advice appreciated.
