I'm confused because according to the M68000PRM moving immediate values to
the transparent translation registers is not supported by the 68030 i.e.

PMOVE TT0,017E8107 PC=0041F1D0

is not a legal instruction. My assembler (the Easy Rider assembler) also
complains with "Adressierungsart nicht zugelassen" when I try

  pmove $017e8107,tt0

But

  pmove $017e8197,tc

works fine, and according to the PRM for the tc this addressing is legal,
indeed.

The current debug output says

PMOVE: write TT0 017E8107

Either this is a misunderstandig on my side or something might still be
wrong in the debug output?

By the way, can you comment on my PRM (1st edition) reserving 6 bits for
the MC68030 FC registers? In one of your previous emails you mentioned
your copy says it's 5 bits, which is what I would have expected. Is
there a newer edition of the PRM available somewhere?

Take care
