Hi Cypress team,
In S29JL064H datasheet page 33, there's the "Data# Polling Algorithm" flow char, as shown below:
At “DQ5=1?", the "No" arrow leads to the beginning of "DQ7=Data?"
-- Is this accurate? I think here we should let it return to the previous read op, viz. it should lead to the "Read DQ7-DQ0 Addr = VA" square after "START".
My guess is confirmed in S29JL064J datasheet page 35 Figure 8, and S29GL01GT datasheet page 39 Figure 7, whose "Data# Polling Algorithm" are as follows:
Can you confirm which flow chart is correct? The Figure 11.1 in S29JL064H datasheet seems inaccurate, can you confirm this?
Thank you & Best Regards~!

Hi xieyl,
Thank you for contacting Cypress Semiconductor.
Yes, your understanding is correct. The correct operation flow should be to read DQ7 - DQ0 again after checking for DQ5 = 1? and then check for DQ7 = Data?
