Preliminary
NOTES:
1. RA : Read Address, PA : Program Address, RD : Read Data, PD : Program Data
DA : Dual Bank Address (A19 - A20), BA : Block Address (A12 - A20), X = Don’t care .
2. To terminate the Autoselect Mode, it is necessary to write Reset command to the register.
3. The 4th cycle data of Autoselect mode is output data.
The 3rd and 4th cycle bank addresses of Autoselect mode must be same.
4. The Read / Program operations at non-erasing blocks and the autoselect mode are allowed in the Erase Suspend mode.
5. The Erase Suspend command is applicable only to the Block Erase operation.
6. DQ8 - DQ15 are don’t care in command sequence, except for RD and PD.
7. A11 - A20 are also don’t care, except for the case of special notice.

3. Addresses must be composed of the Block address (A12 - A20).
The Block Protect and Unprotect operations may be implemented via programming equipment too.
Refer to the "Block Group Protection and Unprotection".
4. If WP/ACC
=

IL,
the two outermost boot blocks is protected. If WP/ACC
=

IH,
the two outermost boot block protection depends on whether those
blocks were last protected or unprotected using the method described in "Block Group Protection and Unprotection". If WP/ACC
=

, all blocks
will be temporarily unprotected.
