   SCSI Terminating Power
   3-4     5-6     Function
   SHORT*  SHORT*  Power is supplied to the terminating resistor from the IDD
                   and TERMPWR pin.  Power is also suppiled to the TERMPWR pi
                   n from the IDD.
   OPEN    SHORT   The TERMPWR pin is not used. Power is supplied to the IDD
                   terrminating resistor only from the IDD.
   SHORT   OPEN    Power is not supplied to the terminating resistor from the
                   IDD, only from the TERMPWR pin.

Notes:
 1. Set the SCSI ID so that there are no duplicates between SCSI devices on
    the same SCSI bus.

 2. The Priority of SCSI bus use during in ARBITRATION phase is determined by
    SCSI ID as follows:
          7 > 6 > 5 > 4 > 3 > 2 > 1 > 0 > 15 > 14 > 13 > 12 > 11 > 10 > 9 > 8
