All PPB must be preprogrammed prior to issuing the All PPB Erase Command.
Figure 9.3 PPB Erase Operation
9.3
Persistent Protection Bit Lock Bit
The Persistent Protection Bit Lock Bit is a global volatile bit for all sectors. When set to "1", it
locks all PPBs; when set to "0", it allows the PPBs to be changed. There is only one PPB Lock Bit
per device.
Notes:
1. No software command sequence unlocks this bit unless the device is in the password pro-
tection mode; only a hardware reset or a power-up clears this bit.
2. The PPB Lock Bit must be set only after all PPBs are configured to the desired settings.
9.4
Dynamic Protection Bits
A Dynamic Protection Bit (DYB) is volatile and unique for each sector and can be individually
modified. DYBs only control the protection scheme for unprotected sectors that have their PPBs
set to "0". By issuing the DYB Set or Clear command sequences, the DYBS are set or cleared,
thus placing each sector in the protected or unprotected state respectively. This feature allows
software to easily protect sectors against inadvertent changes, yet does not prevent the easy
removal of protection when changes are needed.
Notes:
1. The DYBs can be set or cleared as often as needed with the DYB Write Command.
2. When the parts are first shipped, the PPBs are cleared, the DYBs are cleared, and PPB Lock
is defaulted to power up in the cleared state – meaning the PPBs are changeable. The DYB
are also always cleared after a power-up or reset.
3. It is possible to have sectors that are persistently locked with sectors that are left in the dy-
namic state.
