I have problem accessing XRAM in DS89C430. I have included startup.A51 file and followed the instruction under forum "http://www.keil.com/support/docs/3345.htm". The issue is when i debug the code all work fine, but when it comes to hardware, i wont get desired data i wrote into XRAM. The code working well with P89V51RD2, but it is required to have faster processing. Please help.
