Table 13. Protection States
(1)
Note: 1. All blocks are protected at power-up, so the default configuration is 001 or 101 according to WP status.
2. Current state and Next state gives the protection status of a block. The protection status is defined by the write protect in and by
DQ1 (= 1 for a locked block) and DQ0 (= 1 for a protected block) as read in the Read Electronic Signature instruction with A1 = V
IH
and A0 = V
IL
.
3. Next state is the protection status of a block after a Protect or Unprotect or Lock command has been issued or after WP has changed
its logic value.
4. A WP transition to V
IH
on a locked block will restore the previous DQ0 value, giving a 111 or 110.
