As long as V
has passed over the POR threshold, the device is in the following state:
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).
Standby Power mode
deselected (at next power-up, a falling edge is required on Chip Select (S) before any
instruction can be started).

the Write Enable Latch (WEL) is reset to 0
the Write In Progress (WIP) is reset to 0
The SRWD, BP1 and BP0 bits of the Status Register are unchanged from the
previous power-down (they are non-volatile bits)
