1. X Don’t Care, PA Program Address, PD Program Data, BA Any address in the Block. All values in the table are in
hexadecimal.
The Command Interface only uses A–1, A0-A10 and DQ0-DQ7 to verify the commands; A11-A20, DQ8-DQ14 and DQ15
are Don’t Care. DQ15A–1 is A–1 when BYTE is VIL or DQ15 when BYTE is VIH.
