Data Cycles

• Secondary Address (Read/write)
• Random Data (Read/Write)
• Block Transfers - Handshake (Read/Write)

  

  Timing - Typical for Backplane

  Slave:

  Primary Address: AK UP response to AS UP - 40 ns

  Random Data : DK UP response to DS UP - 215 ns read
  DK UP response to DS UP - 140 ns write
  DK DN response to DK DN - 50 ns

  Block Transfer : DK T response to DS T - 120 ns

  Master:

  Random Data : DS DN response to DK UP - 140 ns read
  DS DN response to DK DN - 50 ns write

  Block Transfer : DS T response to DK T - 110 ns

  Maximum Transfer rate (Slave response = 0 ns): 9 Mhz (110 ns/Word).
