When the power supply is turned on, V
Select (S) line is not allowed to float but should follow the V
recommended to connect the S line to V
In addition, the Chip Select (S) input offers a built-in safety feature, as the S input is edge
sensitive as well as level sensitive: after power-up, the device does not become selected
until a falling edge has first been detected on Chip Select (S). This ensures that Chip Select
(S) must have been High, prior to going Low to start the first operation.

In order to prevent inadvertent Write operations during power-up, a power on reset (POR)
