*1 : In CE1s controlled data retention mode, input level of CE2s should be fixed Vccs to VCCs–0.2 V or VSS to 0.2 V
during data retention mode. Other input and input/output pins can be used between –0.3 V to VCCs+0.3 V.
*2 : When CE1s is operating at the VIH Min level, the standby current is given by ISB1s during the transition of VCCs
from Vccs Max to VIH Min level.
