Read operation is in progress.
Special bus operations
Additional bus operations can be performed to read the Electronic signature and also to
apply and remove Block Protection. These bus operations are intended for use by
programming equipment and are not usually used in applications. They require V
applied to some pins.
Electronic signature
The memory has two codes, the manufacturer code and the device code, that can be read
to identify the memory. These codes can be read by applying the signals listed in
and
Block Protect and Chip Unprotect
Groups of blocks can be protected against accidental Program or Erase. The Protection
groups are shown in
Addresses. The whole chip can be unprotected to allow the data inside the blocks to be
changed.
