Note
As defined by the values in the Block Protect (BP2, BP1, BP0) bits of the Status Register, as shown in
Table 9.3
either by setting the SRWD bit after driving W# low, or by driving W# low after setting the SRWD bit.
However, the device disables HPM only when W# is driven high.
Note that HPM only protects against changes to the status register. Since BP2:BP0 cannot be changed in
HPM, the size of the protected area of the memory array cannot be changed. Note that HPM provides no
protection to the memory array area outside that specified by BP2:BP0 (Software Protected Mode, or SPM).
If W# is permanently tied high, HPM can never be activated, and only the SPM (BP2:BP0 bits of the Status
Register) can be used.

Status Register is writable (if the WREN
command has set the WEL bit). The values in
the SRWD, BP2, BP1 and BP0 bits can be
changed.
Status Register is Hardware write protected.
The values in the SRWD, BP2, BP1 and BP0
