* 1.0      	M.Gallop    14/08/01	Original coding                                         
* 1.1	    M.Gallop    08/10/01	Updated SECTIONS names: 
*										DP256_PLL   => DP256_CRG                                                                       
*										DP256_Timer => DP256_TIMER                                                                       
*										DP256_Regs  => DP256_REGS
*									Problem was found because PLL registers
*									were being placed into the RAM space.
*									Changed Regs & Timer to be consistant with 
*									the .prm file
