      Transformer must be a DDC recommended transformer or other
      transformer that provides an equivalent minimum CMRR.
      (8)
      Typical value for minimum intermessage gap time.
      Under software
      control, this may be lengthened to 65,535 ms - message time, in
      increments of 1
      s. If ENHANCED CPU ACCESS, bit 14 of Configuration
      Register #6, is set to logic “1”, then host accesses during BC Start-of-
      Message (SOM) and End-of-Message (EOM) transfer sequences could
      have the effect of lengthening the intermessage gap time. For each host
      access during an SOM or EOM sequence, the intermessage gap time will
      be lengthened by 6 clock cycles. Since there are 7 internal transfers
      during SOM, and 5 during EOM, this could theoretically lengthen the
      intermessage gap by up to 72 clock cycles; i.e., up to 7.2
      s with a 10
      MHz clock, 6.0
      s with a 12 MHz clock, 4.5 s with a 16 MHz clock, or 3.6
      s with a 20 MHz clock.
      (9)
      For Enhanced BC mode, the typical value for intermessage gap time is
      approximately 10 clock cycles longer than for the non-enhanced BC
      mode. That is, an addition of 1.0
      s at 10 MHz, 833 ns at 12 MHz, 625 ns
      at 16 MHz, or 500 ns at 20 MHz.
      (10) Software programmable (4 options).
      Includes RT-to-RT Timeout
      (measured mid-parity of transmit Command Word to mid-sync of
      transmitting RT Status Word).
      (11) Measured from mid-parity crossing of Command Word to mid-sync
      crossing of RT's Status Word.
      (12)
      0JC is measured to the bottom of the case
      (13) External 10
      F Tantalum and 0.1 F capacitors should be located as
      close as possible to Pins 20 and 72, and a 0.1
      F at pin 37. The BU-
      62864 should also have a 0.1
      F at pin 26.
      (14) MIL-STD-1760 requires that the PCI Enhanced Mini-ACE produce a 20
      Vp-p minimum output on the stub connection.
      (15) Power
      dissipation
      specifications
      assume
      a
      transformer
      coupled
      configuration with external dissipation (while transmitting) of 0.14 watts for
      the active isolation transformer, 0.80 watts for the active bus coupling
      transformer, 0.45 watts for each of the two bus isolation resistors and 0.15
      watts for each of the two bus termination resistors.
      (16) The 5V tolerant pins are RTAD0-5, RTAD_PAR, RTAD_LAT, TXINH_A/B,
      and SSFLAG*/EXT_TRIG.
