How to use MC68HC908QY4A ADC in C language

Hello people,
I made a C language program to use the MC68HC908QY4A microcontroller ADC channel, but I could not make the AD channel stay logic level 0 because it always stays 5 volts on the channel pin.
Could anyone inform me or send a routine to make the pin level at 0 volts? For I'm going to inject a variable voltage value into it.

Does anyone know where I can find C language sample programs for this MC68HC08 family?

Thank you very much.
