Power-up and power-down
At power-up and power-down, the device must not be selected (that is Chip Select (S) must
follow the voltage applied on V
A safe configuration is provided in
To avoid data corruption and inadvertent write operations during power-up, a power on reset
(POR) circuit is included. The logic inside the device is held reset while V

Moreover, the device ignores all write enable (WREN), page write (PW), page program (PP),

At power-up, the device is in the following state:
Normal precautions must be taken for supply rail decoupling, to stabilize the V
