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.

3.6.1

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 Table 2

and Table 3, Bus Operations.

3.6.2

Block Protect and Chip Unprotect

Each block can be separately protected against accidental Program or Erase. The whole

chip can be unprotected to allow the data inside the blocks to be changed.

Block Protect and Chip Unprotect operations are described in Appendix C: Block Protection.
