protected against Page Program (PP) and Sector Erase (SE) instructions. The Block Protect
(BP2, BP1, BP0) bits can be written provided that the Hardware Protected mode has not
been set. The Bulk Erase (BE) instruction is executed if, and only if, all Block Protect (BP2,
BP1, BP0) bits are 0.

this mode, the non-volatile bits of the Status Register (SRWD, BP2, BP1, BP0) become
read-only bits and the Write Status Register (WRSR) instruction is no longer accepted for
execution.

Write Status Register (WRSR)
The Write Status Register (WRSR) instruction allows new values to be written to the Status
Register. Before it can be accepted, a Write Enable (WREN) instruction must previously
have been executed. After the Write Enable (WREN) instruction has been decoded and
executed, the device sets the Write Enable Latch (WEL).
The Write Status Register (WRSR) instruction is entered by driving Chip Select (S) Low,
followed by the instruction code and the data byte on Serial Data Input (D).
The instruction sequence is shown in
The Write Status Register (WRSR) instruction has no effect on b6, b5, b1 and b0 of the
Status Register. b6 and b5 are always read as 0.
Chip Select (S) must be driven High after the eighth bit of the data byte has been latched in.
If not, the Write Status Register (WRSR) instruction is not executed. As soon as Chip Select
(S) is driven High, the self-timed Write Status Register cycle (whose duration is t
initiated. While the Write Status Register cycle is in progress, the Status Register may still
be read to check the value of the Write In Progress (WIP) bit. The Write In Progress (WIP)
