Table 8. Block Lock Status
Table 9. Protection Status
Note: 1. The protection status is defined by the write protect pin and by DQ1 (‘1’ for a locked-down block) and DQ0 (‘1’ for a locked block)
Current State
2. All blocks are locked at power-up, so the default configuration is 001 or 101 according to WP status.
3. A WP transition to V
