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 is the average current required for the duration of the SoftStore STORE cycle.

IH will not produce standby current levels until a software initiated 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.
