connect ADC0808 and PIC18F4550

13 adc channel in pic18f4550

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!

Why use external ADC when you have 13 Channel ADC inside 18F4550!

Because I want to do DAC again so the resolution of ADC and DAC should be the same.

You still can use internal ADC. Ignore least 2 significant bits and you get 8-bit of data!
