b: ICC1 and ICC3 are depedent on output loading and cycle rate. The specified values are obtained with outputs unloaded.
The current ICC1 is measured for WRITE/READ - ratio of 1/2.
c: ICC2 and ICC4 are the average currents required for the duration of the respective STORE cycles (STORE Cycle Time).
d: Bringing E ≥ VIH will not produce standby current levels until any nonvolatile cycle in progress has timed out. See MODE SELECTION
table. The current ICC(SB)1 is measured for WRITE/READ - ratio of 1/2.
