L = Logic Low = VIL, H = Logic High = VIH, X = Don’t care.
Notes:
1. DQ31–DQ16 are HIGH Z when WORD# = VIL
2. When WORD# = VIL, DQ31-DQ16 are floating
3. WP# controls the two outermost sectors of the top boot block or the two outermost sectors of the bottom boot block.
4. DQ0 reflects the sector PPB (or sector group PPB) and DQ1 reflects the DYB
5. Addresses are A0:A18 for the x32 mode and A–1:A18 for x16 mode.
