Notes:
1.
Refer to the Query Structure Output section and offset 28h for the detailed definition of offset address as a
function of device bus width and mode.
2.
BA = Block Address beginning location (i.e., 02000h is block 2’s beginning location when the block size is
128 Kbyte).
3.
Offset 15 defines “P” which points to the Primary Numonyx-Specific Extended Query Table.
