- * @brief	GDISP emulation routines for stuff the driver dosen't support

- *

- * @addtogroup GDISP

- *

- * @details	Even though this is a software emulation of a low level driver

- *			most validation doesn't need to happen here as eventually

- *			we call a real low level driver routine and if validation is

- *			required - it will do it.
