      SIMPLE SYSTEM INTERFACE
      FIGURE 17 illustrates the capability of the SSRT to interface to
      a system with no host processor in burst mode. In this example,
      only one set of external latches is needed to buffer the data
      words written by the SSRT to the external system. In burst mode,
      all received data words are stored in the internal FIFO until the
      last word is received. At this point, the SSRT will transfer the
      entire contents of the FIFO to the system if the message is vali-
      dated. In this case, GBR will be driven low for two clock cycles
      following the burst transfer cycle.
      If the received message is not valid, the FIFO data will not be
      transferred to the external system and GBR will remain high.
