New Feature in SDR SDRAM Controller Verilog Reference Design version 1.1
=============================================================================

The SDR SDRAM Controller Reference Design version 1.1 issues a Burst terminate command to the SDRAM device when the device is
in Page Mode operation.  In a Page Mode operation, in order to terminate the burst transfer, the user needs to issue a 
precharge command as described in the \doc\SDR_SDRAM.pdf.  The controller will then issue a Burst Terminate command to 
the SDRAM device. In the previous version, the SDR SDRAM controller will issue a precharge to the SDRAM device in order to stop the burst.
