Although I do program in BASIC, C and in the past PASCAL, I have never done anything in assembler.

Rather than learn something new, I am using MSC-52 Basic on a 80C32. There is an assembler routine that I would like to call from basic to read values from an ADC.

I know how to call the routine, but what I am not sure of is how to pass the data through r0 and r1 to and from the ADC.

Any help would be greatly appreciated.
