Bus Operations

3.6
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 VID to be
applied to some pins.
3.7
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 Tables
and Table 3., Bus Operations.
3.8
Block Protection and Block Unprotection.
Each block can be separately protected against accidental Program or Erase. Protected
blocks can be unprotected to allow data to be changed.
There are two methods available for protecting and unprotecting the blocks, one for use on
programming equipment and the other for in-system use. Block Protect and Blocks
Unprotect operations are described in Appendix Appendix C.
