I am working to port older code to an Atmel AT89C51AC3, I have the
system basically running but have run out of data space while
tweaking the code to handle timing constraints. The AT89C51AC3 has
2048 bytes of ERAM that I was expecting to be able to use, but I have
not found the correct compiler and/or linker configuration to get it
working. I have seen comments in other threads that state BOTH:
- PDATA and XDATA can be used together
- PDATA and XDATA can NOT be used together
