1. X don’t care, PA Program Address, PD Program Data, BA any address in the block.
2. All values in the table are in hexadecimal.
3. The command interface only uses A–1, A0-A10 and DQ0-DQ7 to verify the commands; A11-A19, DQ8-
DQ14 and DQ15 are Don’t Care. DQ15A–1 is A–1 when BYTE is VIL or DQ15 when BYTE is VIH.

8. After the Unlock Bypass Reset command read the memory as normal until another command is issued.
