For now I've chosen 0x15 and 0x16 for the AECR and AESR regs, respectively, but it would be no problem to change it. One nit: CYMACADDE should come before OVMACADDE, for consistency with the others. Another nit: l.addc probably shouldn't trigger an exception when CY is set, even if the CYADDE flag is on. That instruction is meant to be chained with other l.addc instructions, so it doesn't seem useful to raise the exception in that case. -Pete
