Hello,

I am new to using EASy68K as a way to debug some old 68020 code. I have a couple of instructions the seem to be giving it a headache and throwing errors.
They are

Code:
MOVEC       %D0,%CACR

and

MOVEC       %A2,%VBR


The CACR throws an illegal instruction

and the VBR says "Emulator exception occurred at location 40534. Execution halted"

I was wondering if it was possible to allow code with these instruction to execute somehow

Thanks
CG.

Sorry, EASy68K emulates the 68000 only.
