Note
VA = Valid address. Illustration shows first status cycle after command sequence, last status read cycle, and array data read cycle.
Note
VA = Valid address; not required for DQ6. Illustration shows first two status cycle after command sequence, last status read cycle, and array
data read cycle.
Note
The system may use CE# or OE# to toggle DQ2 and DQ6. DQ2 toggles only when read at an address within an erase-suspended sector.
