POWER-UP AND DELIVERY STATE

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

–

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 Reg-

ister are unchanged from the previous power-

down (they are non-volatile bits).

Initial Delivery State

The device is delivered with the memory array set

at all 1s (FFh). The Status Register Write Disable

(SRWD) and Block Protect (BP1 and BP0) bits are

initialized to 0.
