Notes:
1. Output voltage (open drain or open collector) condition = 3 mA sink current.
2. Refer to the
MPC8544E PowerQUICC III Integrated Communications Host Processor Reference Manual for information on
the digital filter used.
3. I/O pins will obstruct the SDA and SCL lines if OVDD is switched off.
