tended Block mode the Boot Blocks are not acces-
sible.
To exit from the Extended Block mode the Exit Ex-
tended Block command must be issued.
The Extended Block can be protected, however
once protected the protection cannot be undone.
Exit Extended Block Command
The Exit Extended Block command is used to exit
from the Extended Block mode and return the de-
vice to Read mode. Four Bus Write operations are
required to issue the command.
Block Protect and
Chip Unprotect Commands
Groups of blocks can be protected against acci-
dental Program or Erase. The Protection Groups
are shown in
APPENDIX A.
,
Table 19.
and
Table
20., Bottom Boot Block Addresses, M29W640DB
.
The whole chip can be unprotected to allow the
data inside the blocks to be changed.
Block Protect and Chip Unprotect operations are
described in
APPENDIX D.
.

Note: X Don’t Care, PA Program Address, PD Program Data, BA Any address in the Block. All values in the table are in hexadecimal.
The Command Interface only uses A–1, A0-A10 and DQ0-DQ7 to verify the commands; A11-A20, DQ8-DQ14 and DQ15 are Don’t
Care. DQ15A–1 is A–1 when BYTE is V
