Temporary Sector Group Unprotect
(Note: In this device, a sector group consists of four adjacent
sectors that are protected or unprotected at the same time
(see
This feature allows temporary unprotection of previ-
ously protected sector groups to change data in-sys-
tem. The Sector Group Unprotect mode is activated by
setting the RESET# pin to V
this mode, formerly protected sector groups can be
programmed or erased by selecting the sector group
addresses. Once V
