Sonix SN8P2501 cpu

[Git]

Don't know how true it is, but I just read this :

SN8P2501B pin is fully compatible EM78P153S (PIC12C508)

It doesn't seem to share all mnemonics with PIC, but it could still be 100% binary compatible.

Some of the mnemonics are definitely non-PIC, but that could just be their way of trying to make it look different (as happened with the Z80/8080).

Looking again at those mnemonics and (probably) more importantly the description, it does appear to be very much like a PIC. I notice the stack only supports one level of push/pop - again, PIC like.

Did you find any instruction encoding? I'd say it would be sensible to feed your code image through a PIC disassembler and see what comes out.
