Hi
How to access rom memory from C program. I would like to access to sine table
located at FFED00h addres in memory space, but I can not find in compiler doc.
how to create pointer to rom memory.
MPNMC bit is cleared of course.
Kind Regards
/Greg

int *p = (int*)0xFFED00;
gives:
, line 49: warning:
conversion from integer to smaller pointer
int *p = (int*)0xFFED00;
That's why I asked, but I think I uderstand now, i use small model where pointer is 16bit, this way will works only with large model or huge model.
In small mode propably some asembler macro needs to be use.
