Is the fftpts_in signal a counter

Honored Contributor II

I was reading through the FFT ip core guide (https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/ug/ug_fft.pdf) and looked at table 3-2. I could not determine if the signal was a counter of how many points have gone through the core or if the input remains constant, assuming that I want the same n-point FFT for the entire time.
