I have read the application document: AN87216" Designing a GPIF™ II Master Interface ",when I read the state machine of the master slave FIFO Interface, I am confused with the state "COUNT_HIT" in the writing part of the whole state machine. Why add this state in writing process? and there is no correspongding one in the reading process?

It seems like the COUNT_HIT state is redundant.

I tried removing it and the data transfer worked fine for both full and short packets.

However, I will need to check with the author about why this state is present. I will update this thread accordingly.
