Code:

/*
Mirror byte for PIC12/14/16
For PIC18 will not work
*/
#bit _C=STATUS.0
#define _RLF_F(data) #asm rlf data,F #endasm
#define _RRF_F(data) #asm rrf data,F #endasm
int8 MirroByte(int8 value) {
int8 i,mirror;
i = 8; mirror = 0;
do {
_RLF_F(value);
_RRF_F(mirror);
} while( --i );
return mirror;
}
/*
For PIC18 change _RLF_F & _RRF_F to
#define _RLCF_F(data) #asm rlcf data,F #endasm
#define _RRCF_F(data) #asm rrcf data,F #endasm

This is almost certainly a student-type question, which has been
answered before. So you can find it with the forum's search engine.
Just don't search for a word like "mirrored". Use more common
words in the search string, such as: Reverse bits
Then set it to "Search for all terms".

Here are some typical results. If you use the search engine
you can easily find the answers.
