Table 6. WP#/ACC Modes
Temporary Sector Unprotect
(Note: For the following discussion, the term “sector” 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 Table 5).
This feature allows temporary unprotection of previously protected sectors to
change data in-system. The Temporary Sector Unprotect mode is activated by
setting the RESET# pin to
"VID" section. During this mode, formerly protected
sectors can be programmed or erased by selecting the sector addresses. Once
VID is removed from the RESET# pin, all the previously protected sectors are
protected again. Figure 2 shows the algorithm, and Figure 25 shows the timing
diagrams, for this feature. If the WP#/ACC pin is at VIL, sectors 0, 1, 140, and
141 will remain protected during the Temporary sector Unprotect mode.
WP# Input Voltage
Device Mode
VIL
Disables programming and erasing in SA0, SA1, SA140, and SA141
VIH
Enables programming and erasing in SA0, SA1, SA140, and SA141, dependent on
whether they were last protected or unprotected.
VHH
Enables accelerated progamming (ACC). See “Accelerated Program Operation” on
Notes:
1. All protected sectors unprotected (If WP#/ACC = VIL, sectors 0, 1, 140, and 141 will remain protected).
2. All previously protected sectors are protected once again.
