1701 flip flop

I am trying to make a simple LED flasher using the ADAU1701, and seem to be missing something rather basic.


I used the duty cycle idea found here


But, when I try to make the tone generator go less then about 300Hz, it seems to fail (I guess the counter isn't large enough.)


Anyway, I am trying to use two timers with external reset but when I try to feedback the second to the first, I get an "Illegal feedback loop detected" error.


I want the LED to flash at about 50% duty cycle at 1 Hz.


Any Ideas?


Thanks, Mark.
