;; Version: 1.4, Updated on 2006/06/09 at 09:53:12
;; Generated by PSoC Designer ver 4.4 b1884 : 14 Jan, 2007
;;
;; DESCRIPTION: LCD User Module software implementation file
;; for the M8C based PSoC family of devices.
;;
;; This set of functions is written for the common 2 and 4 line
;; LCDs that use the Hitachi HD44780A controller.
;;
;; LCD connections to PSoC port
;;
;; PX.0 ==> LCD D4
;; PX.1 ==> LCD D5
;; PX.2 ==> LCD D6
;; PX.3 ==> LCD D7
;; PX.4 ==> LCD E
;; PX.5 ==> LCD RS
;; PX.6 ==> LCD R/W
;;
;; 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.
