;;  DESCRIPTION: DigitalBuffers User Module software implementation file
;;               for the 22/24/27/28xxx 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.

;  FUNCTION NAME: DigBuf_EnableInt
;
;  DESCRIPTION:
;     Enables the DigBuf's interrupt by setting the interrupt enable mask bit
;     associated with this User Module. This function has no effect until and
;     unless the global interrupts are enabled (for example by using the
;     macro M8C_EnableGInt).
;-----------------------------------------------------------------------------
;
;  ARGUMENTS:    None.
;  RETURNS:      Nothing.
;  SIDE EFFECTS:
;    The A and X registers may be modified by this or future implementations
;    of this function.  The same is true for all RAM page pointer registers in
;    the Large Memory Model.  When necessary, it is the calling function's
;    responsibility to perserve their values across calls to fastcall16 
;    functions.
