Notes: 1. Performing successive read operations from any address will cause DQ6 to toggle.
2. Reading the byte address being programmed while in the erase-suspend program mode will indicate
logic “1” at the DQ2 bit. However, successive reads from the erase-suspended sector will cause DQ2 to
toggle.
3. DQ0 and DQ1 are reserve pins for future use.
4. DQ4 is Fujitsu internal use only.
