It is described on page 47 of the above flash ROM data sheet "Document Number: 002-01522 Rev. * B".

According to Figure 9.1 Write Buffer Programming Operation

When DQ5 = 1, it is written to read DQ15-DQ0 again. Is a delay necessary?

The answer is that no delay is needed.

After writing to the flash with Write Buffer Programming, there is an address called data polling that allows you to check if it was written.

Therefore, you can check it by data polling, so no delay is required.

Please refer to page 59 of the following data sheet for data polling.

(Data polling is a bit status that confirms whether the program has completed writing.)
