** device which is used then any necessary transformations (e.g.
** shifting) are done.
** Parameters :

** Data - User data.
** Returns :
** --- - Error code, possible codes:
** - ERR_OK - OK.
** - ERR_SPEED - This device does not work in
** the active clock configuration.
** - ERR_DISABLED - Component or device is
** disabled.

** ===================================================================
** Method : DA1_SetBuffer (component DAC_LDD)
**
** Description :
** Writes an array of data words to the data buffer registers.
** Array is defined by pointer to start address and by it's
** length. First written data buffer register is defined by
** index.
** If the length of array exceeds number of registers between
** the first written register and the last one at the end of
** the buffer then an ERR_PARAM_RANGE is returned and no data
** are written. It is possible to write all register available
** in hardware - no checking for current upper limit value of
** buffer is done.
** DataArrayPtr has fixed data type regardless of current
** hardware or design time configuration and must be always
** used. Real type of user data is specified in <Data mode>
** property.
** If the DMA service is enabled then this methods can be used
** to prepare DMA transfer via channel handled by DMA Transfer
** inherited component.
** _/Note: This method is available only if DAC device is
** supporting data buffer and Data buffer is enabled./_
** Parameters :
** NAME - DESCRIPTION
** * DeviceDataPtr - Device data structure
** pointer returned by <Init> method.
** * DataArrayPtr - Pointer to array
** containing user data.
** DataArrayLength - Length of user
** data array which should be written to data
** buffer.
** FirstRegisterIndex - Index of
** first written data buffer register.
** Returns :
** --- - Error code, possible codes:
** - ERR_OK - OK.
** - ERR_SPEED - This device does not work in
** the active clock configuration.
** - ERR_DISABLED - Component or device is
** disabled.
** - ERR_PARAM_RANGE - Index of last written
** buffer register would be out of buffer
** range.
