Notes:

1. BA = Block address of the block to be erased.

2. When the boot block lockout feature is enabled, the boot block will not be erased when a chip erase

command or a block erase command for boot block erasure is issued. Once the boot block is not

protected, the boot block will be erased when a chip erase command or a block erase command for

boot block erasure is issued.

3. After completion of the boot block lockout enable or detection command, the Product ID Exit com-

mand must be issued to return to standard read mode.

4. BA = Block address of the boot block;

For top boot block location, A0 = “0”, A1 = “1”, and A14-A18 = “1” where A2-A13 = Don’t Care;

For bottom boot block location, A0 = “0”, A1 = “1”, and A14-A18 = “0” where A2-A13 = Don’t Care.

5. I/O0 = “1” means boot block lockout is enabled, I/O0 = “0” means boot block lockout is disabled.

6. Either one of the Product ID Exit command can be used.
