Autoselect Mode
The autoselect mode provides manufacturer and de-
vice identification, and sector protection verification,
through identifier codes output on DQ7โ€“DQ0. The au-
toselect codes can be accessed in-system through the
command register. Refer to the Autoselect Command
Sequence section for more information.Sector/Sector
Block Protection and Unprotection
(Note: For the following discussion, the term โ€œsectorโ€
applies to both sectors and sector blocks. A sector
block consists of two or more adjacent sectors that are
protected or unprotected at the same time (see Tables
8 and 9).
Table 8.
Top Boot Sector/Sector Block Addresses
for Protection/Unprotection
Table 9.
Bottom Boot Sector/Sector Block
Addresses for Protection/Unprotection
The hardware sector protection feature disables both
program and erase operations in any sector. The hard-
ware sector unprotection feature re-enables both
program and erase operations in previously protected
sectors. Sector protection and unprotection can be im-
plemented as follows.
Sector protection/unprotection requires V
ID on the RE-
SET# pi n only, and c an be i mplem ented ei th er
in-system or via programming equipment. Figure 2
shows the algorithms and Figure 26 shows the timing
diagram. This method uses standard microprocessor
bus cycle timing. For sector unprotect, all unprotected
sectors must first be protected prior to the first sector
unprotect write cycle. Note that the sector unprotect
algorithm unprotects all sectors in parallel. All previ-
o u s l y pr ot e c te d s e c t or s m u s t be i n d i v i du al l y
re-protected. To change data in protected sectors effi-
ciently, the temporary sector un protect function is
available. See โ€œ Temporary Sector/Sector B lock
Unprotectโ€.
The device is shipped with all sectors unprotected.
It is possible to determine whether a sector is pro-
tected or unprotected. See the Autoselect Mode
section for details.
Write Protect (WP#)
The Write Protect function provides a hardware
method of protecting certain boot sectors without
using V
ID. This function is one of two provided by the
WP#/ACC pin.
