Preliminary
device will latch in address and data and program the specified location. The allowable addresses
are shown in
Table 20
or
Table 21
. See
Figure 14,
“
Protection Register Programming Flowchart
”
on page 37
Any attempt to address Protection Program commands outside the defined protection register
address space will result in a status register error (program error bit SR.4 will be set to 1).
Attempting to program a locked protection register segment will result in a status register error
(program error bit SR.4 and lock error bit SR.1 will be set to 1).
4.15.3
Locking the Protection Register
The user-programmable segment of the protection register is lockable by programming Bit 1 of the
PR-LOCK location to 0. Bit 0 of this location is programmed to 0 at the Intel factory to protect the
unique device number. Bit 1 is set using the Protection Program command to program
“
FFFD
”
to
the PR-LOCK location. After these bits have been programmed, no further changes can be made to
the values stored in the protection register. Protection Program commands to a locked section will
result in a status register error (program error bit SR.4 and Lock Error bit SR.1 will be set to 1).
Protection register lockout state is not reversible.
