;;  DESCRIPTION: Assembler source for the ADCINC A/D Converter
;;               User Module with 1st-order modulator.
;;
;;  NOTE: User Module APIs conform to the fastcall16 convention for marshalling
;;        arguments and observe the associated "Registers are volatile" policy.
;;        This means it is the caller's responsibility to preserve any values
;;        in the X and A registers that are still needed after the API
;;        function returns. Even though these registers may be preserved now,
;;        there is no guarantee they will be preserved in future releases.
