Hi again. I have a custom 8051 processor which has defined a series of sfr, such as "sfr id_custom = 0x32" in the header reg51.h file. When I tried to access from C, throws the error "Error 146: Invalid Base Address". As I can do to disable this protection? or enabling the access to these registers? Thanks.
PS: Sorry about my english. =)
Thanks for your answer, it's very useful. Gonzalo.
