I'm about to use the external chip ADC0808 (ADC chip) to convert an audio signal form the phone line digital signal. I want to connect this chip to PIC18F4550. My question is do I need to write any code (in C code) to configure the connection between these 2 chips or I just connect ADC0808 to one of the ports of the PIC18F4550 and by programming the PIC18F4550 and read the connected pins with the ADC0808. Any help would be very happy. Thank you all!

Just read the outputs of the ADC with the PIC. If the ADC has an output signal to indicate when the its digital output will change use it as not to read the digital output during a transition.
