(1) For operation between specified voltage ranges, refer to the worst-case parameter in both applicable ranges.

(2) The power-on reset circuit resets the I²C bus logic with V_CC < V_PORF.

(3) C_io(ON) depends on internal capacitance and external capacitance added to the SCn lines when channels(s) are ON.

(4) RESET = V_CC (held high) when all other input voltages, V_I = GND.
