+ * \brief HX8347 low-level hardware macros for Atmel SAM3X-EK board.
+ *
+ * The LCD controller is connected to the cpu static memory controller.
+ * LCD has 16 data lines and usual RS/WR/RD lines.  The data lines
+ * are connected to the SMC data bus (D0-15), while the SCM address bus
+ * (A1 only) is used to drive the RS pin.  WR/RD are connected to SMC's
+ * NWE and NRD respectively.
