How would I locate a structure to coincide with the beginning of SFR space for the 8051? address 0x80 of directly assessible data memory.
We are using a core8051 (inside an FPGA), and the core8051 lets us map external events to SFR space. So it would be very convienent to define a structure which allows us to more easily access all of SFR space. (we take care not to "stomp" on already defined SFR registers.
How can I do that?
Thanks
