time
For proper operation of internal reset functions, VCCA and
VCCD (which must be applied simultaneously) may not be
applied after VCCmod.
Normally, all VCC lines will come up at the same time.
However, due to the possibility of a Standby VCC to be
applied to the VCCmod pin, care should be ensured that
VCCmod is not applied before VCCA and VCCD (which must be
tied together). See the timing diagram and DATA
RETENTION function description.
Note that VCCA/D and VCCmod must be activated above 4.5
V for a least 30 msecs before the device can operate
correctly in Standby Mode.
