/***************************************************************************

  Many games use a master-slave CPU setup. Typically, the main CPU writes
  a command to some register, and then writes to another register to trigger
  an interrupt on the slave CPU (the interrupt might also be triggered by
  the first write). The slave CPU, notified by the interrupt, goes and reads
  the command.
