NOTES:
1. Read timing characteristics during program suspend and erase suspend are the same as during read-only operations.
2. Refer to command definition table (Table 6) for valid AIN or DIN.
3. Sampled, but not 100% tested.
4. Write pulse width (tWP) is defined from CE# or WE# going low (whichever goes low last) to CE# or WE# going high
(whichever goes high first). Hence, tWP = tWLWH = tELEH = tWLEH = tELWH. Similarly, Write pulse width high (tWPH) is defined
from CE# or WE# going high (whichever goes high first) to CE# or WE# going low (whichever goes low first). Hence, tWPH =
tWHWL = tEHEL = tWHEL = tEHWL.
