Inline assembly function and error messages E0551219 and E0550249 (CC-RL)
Last Updated:05/10/2017
Question:
I am using the CC-RL compiler for RL78 devices. When I access an SFR from an inline assembly function, I get the error message E0551219 or E0550249. How do I resolve this?
E0551219: Illegal label reference.
E0550249: Illegal syntax.
Answer:
The code covered by #pragma inline_asm in the C source code is subject to processing by the compiler’s pre-processor.
To access an SFR from code covered by #pragma inline_asm, define the #pragma inline_asm function before including iodefine.h.
[ Example ]
#pragma inline_asm asmfunc_01
void asmfunc_01(void)
{
CLR1 IF0H.7
}
#include ""iodefine.h"
