Are you talking about SH4 interrupts or Potoato interrupts now? (Note
that both the DC and the VMS have dedicated hardware to handle the
communication. On the DC, you have DMA to do the communication, on the
DC the "Work RAM" memory is used for incoming and outgoing messages.
The actual message exchange is all done in hardware.
