Note 4: Parameter guaranteed by design. tOSLH |tPLHmax tPLHmin|; tOSHL |tPHLmax tPHLmin|
Note 5: CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load. Average
operating current can be obtained by the equation: ICC (opr.) CPD * VCC * fIN ICC/8 (per bit).
