For operation between specified voltage ranges, refer to the worst-case parameter in both applicable ranges.
The power-on reset circuit resets the I2C bus logic with VCC < VPORF.
Cio(ON) depends on internal capacitance and external capacitance added to the SCn lines when channels(s) are ON.
RESET = VCC (held high) when all other input voltages, VI = GND.
