Enable MAC in Compiler Does Not Work

Last Updated: June 12, 2011
Question: 

I cannot get the enable MAC to work.

Answer: 

The enable MAC checkbox used with Project > Settings > Compiler tab has limited functionality. The variable where the result is stored must be a 'signed char' to conduct the fast multiply operation.
