Table 9. Block Lock Status
Table 10. Protection Status
Note: 1.
The lock status is defined by the write protect pin and by DQ1 (‘1’ for a locked-down block) and DQ0 (‘1’ for a locked block) as read
in the Read Electronic Signature command with A1 = V
IH
and A0 = V
IL
.
2. All blocks are locked at power-up, so the default configuration is 001 or 101 according to WPF status.
3. A WPF transition to V
IH
on a locked block will restore the previous DQ0 value, giving a 111 or 110.
