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?
At this point I believe all the fly *** has been removed from the pepper. Moving along now.
