;;  DESCRIPTION: USB Device User Module software implementation file
;;               for the CY8C24090 and CY7C64215 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.
