NOTES:

1. Manufacturer and device codes may also be accessed via a command register write sequence. Refer to Table 1.

2. VID is the Silicon-ID-Read high voltage, 11.5V to 12.5V.

3. Refer to Table 1 for valid Data-In during a write operation.

4. X can be VIL or VIH.

5. Code=00H means unprotected.

Code=01H means protected.

6. Refer to chip protect/unprotect algorithm and waveform.

Must issue "unlock for chip protect/unprotect" command before "chip protect/unprotect without 12V system"

command.

7. The "verify chip protect/unprotect without 12V system" is only following "chip protect/unprotect without 12V sys-

tem"

command.
