b: ICC1 and ICC3 are dependent 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 STORE cycle (tSTORE).
d: Bringing E ≥ VIH will not produce standby current levels until any nonvolatile cycle in progress has timed out.
The current ICC(SB)1 is measured for WRITE/READ - ratio of 1/2.
