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 requird for the duration of the STORE cycle (STORE Cycle Time).
d:

IH 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.
