The FIXPEC directive causes the C166 Compiler to avoid
potential problems with JMP to JMP instructions.
When using optimizer level 7 the compiler may generate JMPs to
functions instead of CALLs. If the function begins with a JMP
instruction, you may experience a problem with the PEC (on some chip
steps) that has to do with JMP to JMP instruction sequences. The
FIXPEC directive avoid this problem.
