7 Power-up and delivery state
7.1 Power-up state
After power-up, the device is in the following state:
• Standby power mode,
• deselected (after power-up, a falling edge is required on Chip Select (S
) before any
instructions can be started),
• not in the Hold condition,
• the Write Enable Latch (WEL) is reset to 0,
• 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).

The device is delivered with the memory array bits and identification page bits set to all 1s
(each byte = FFh). The Status Register Write Disable (SRWD) and Block Protect (BP1 and
BP0) bits are initialized to 0.
