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).
