;
;  DESCRIPTION: CSD 2X User Module software implementation file
;;               for the 22x45 PSoC family of devices.
;
;  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 functions
;        returns. For Large Memory Model devices it is also the caller's
;        responsibility to perserve any value in the CUR_PP, IDX_PP, MVR_PP and
;        MVW_PP registers. Even though some of these registers may not be modified
;        now, there is no guarantee that will remain the case in future releases.
