Table 10. Lock 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 Auto Select command with A1 = VIH and A0 = VIL.

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 VIH on a locked block will restore the previous DQ0 value, giving a 111 or 110.
