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.
