If the Password Mode Locking Bit is not set, including
Persistent Protection Mode, the PPB Lock Bit is
cleared after power-up or hardware reset. The PPB
Lock Bit is set by issuing the PPB Lock Bit Set com-
mand. Once set the only means for clearing the PPB
Lock Bit is by issuing a hardware or power-up reset.
The Password Unlock command is ignored in Persis-
tent Protection Mode.
High Voltage Sector Protection
Sector protection and unprotection may also be imple-
mented using programming equipment. The proce-
dure requires high voltage (V
ID
) to be placed on the
RESET# pin. Refer to Figure Note: for details on this
procedure. Note that for sector unprotect, all unpro-
tected sectors must first be protected prior to the first
sector write cycle.
