AS3340 VCO Square output help needed

Pin 5 is the CV for the PWM output, and the effective range (measured on the pin) is 0-4 V for a 12 V supply. See this thread:

Does the pulse width pot do anything? (the voltage from that one is mixed with the CV in by the second TL072, see here:

If the pot doesn’t do anything, check the wiring for the pulse width and PWM CV pots.
