Notes:
1. Output voltage (open drain or open collector) condition = 3 mA sink current.
2. CB = capacitance of one bus line in pF.
3. Refer to the
MPC8360E Integrated Communications Processor Family Reference Manual for information on the digital filter
used.
4. I/O pins will obstruct the SDA and SCL lines if OVDD is switched off.
