I
CC1
and I
CC3
are depedent on output loading and cycle rate. The specified values are obtained with outputs unloaded.
The current I
CC1
is measured for WRITE/READ - ratio of 1/2.
I
CC2
is the average current required for the duration of the STORE cycle (STORE Cycle Time).
Bringing E

will not produce standby current levels until any nonvolatile cycle in progress has timed out. See MODE SELECTION able.
The current I
