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/0000H means unprotected.
Code=01H/0001H means protected.
A15~A12=Sector address for sector protect.
6. Refer to sector protect/unprotect algorithm and waveform.
Must issue "unlock for sector protect/unprotect" command before "sector protect/unprotect without 12V system" command.
7. The "verify sector protect/unprotect without 12V sysytem" is only following "Sector protect/unprotect without 12V system"
command.
