Hi All,


I have an ADAU1701 and need a GPIO pin to output high for +/- 1 sec. after every +/- 10 sec. 


The available timer isn't able to loop by itsself so I came up with the following schematic:



When I test it the 1 doesn't seem to get any further than ReadBack2_2 and doesn't loop. How do I solve this or is there an easier way to get the described functionality?


btw. the mute is just there to be able to send a new 1 to the 1st timer.
