Figure 1.2  Current fluctuation (Typ.) at +5 V when power is turned on 
 
(6)  Power on/off sequence 
The voltage detector circuits monitor +5 V.  The circuits do not allow a write 
signal if either voltage is abnormal.  These prevent data from being destroyed and 
eliminate the need to be concerned with the power on/off sequence.
