when I tried to declare a new variable

unsigned char data testfd6;

the address space overflows
how come? idata works fine
I know idata is the whole 256 byte space
and data is the first 128 byte of memory space

and there is obviously space(gap) in the first 128byte of
memory space

can someone help???
