divide a 10 Mhz signal by 1000 ...

[richard]

I would like to understand why I see all those "counts" for one division

its not one division its three with a 90 deg phase shift on one of them.

one div would be like this

;In simple terms  toggle a pin on every 125th cycle
;start:;set gpio pin high
;delay 124 cycles
;set gpio pin low
;delay 122 cycles
;goto start
