I'm using the tomar microcontroller S12VR for my application.
I need to fill the flash memory not used with NOP and JMP at start up address instructions.
I have modified the .prm file with the FILL directive.
The fill directive required hexadecimal values but I don't know which are the corrispettive values.
I have tested the FILL directive with an example value (0x55) and it is work.
Could you help me?
Thanks in advance
for mor details please look into https://www.nxp.com/docs/en/reference-manual/S12XCPUV2.pdf
NOP has machine code 0xA7
JMP has two different machine codes on the basis of operand:
JMP opr16a 06 hh llJMP oprx0_xysp 05 xb JMP oprx9,xysp 05 xb ffJMP oprx16,xysp 05 xb ee ff JMP [D,xysp] 05 xbJMP [oprx16,xysp] 05 xb ee ff
If you want to jump to a direct address, if I understand you well, then you should put there 05 hh ll where hh ll represents address of the function in a non banked memory.
