Power-down
At power-down (continuous decrease in V
operating voltage to below the power on reset threshold voltage, the device is reset and
stops responding to any instruction sent to it. During power-down, the device must be
deselected (the Chip Select (S) should be allowed to follow the voltage applied on V
in Standby Power mode (that is, there should be no internal Write cycle in progress).
As an extra protection, the Reset (RESET) signal can be driven low for the whole duration of
the power-up and power-down phases.
