I'm currently running a SiLabs C8051F336 processor using the CX51 compiler. I'm getting and illegal op-code (A5-the EMOV instruction) when I compile the following line:
*string = map_char_to_index(*string, font);
this get compiled as
; SOURCE LINE # 77 001E AD00 R MOV R5,font 0020 120000 R LCALL _map_char_to_index 0023 AB00 R MOV R3,string 0025 AA00 R MOV R2,string+01H 0027 A900 R MOV R1,string+02H 0029 EF MOV A,R7 002A A558 EMOV @PR0,A
Any ideas as to why that instruction is implemented on a non MX core, and non Phillips device? How do I disable it?
SiLabs process for loading code into the UC.

Download -- at this point a status dialog appears there are several steps in this process. 1) processing OMF file... 2) writing flash blocks... 3) verifying flash blocks... 4) updating system information...
disconnect and run like the wind... ideally
