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.
6. Refer to sector protect/unprotect algorithm and waveform.
7. The "verify sector protect/unprotect without 12V sysytem" is only following "Sector protect/unprotect without 12V system" com-
P/N: PM0547
mand.
Code=01H means protected.
A17~A13=Sector address for sector protect.
