      Control Register Bit Definitions
      Register 0 (00h)
      BIT NAME
      TYPE* DESCRIPTION
      d7 Downstream
      R
      Indicates if upstream bus is connected
      Connected
      to any downstream buses
      0 = upstream bus disconnected from
      all downstream buses
      1 = upstream bus connected to one or
      more downstream buses
      d6 ALERT1 Logic State
      R
      Logic state of ALERT1 pin, noninverting
      d5 ALERT2 Logic State
      R
      Logic state of ALERT2 pin, noninverting
      d4 Reserved
      R
      Not Used
      d3 Reserved
      R
      Not Used
      d2 Failed Connection
      R
      Indicates if an attempt to connect to a
      Attempt
      downstream bus failed because the
      “Connection Requirement” bit in
      Register 2 was low and the
      downstream bus was low
      0 = Failed connection attempt occurred
      1 = No failed attempts at connection
      occurred
      d1 Latched Timeout
      R
      Latched bit indicating if a timeout has
      occurred and has not yet been cleared.
      0 = no latched timeout
      1 = latched timeout
      d0 Timeout Real Time
      R
      Indicates real-time status of Stuck Low
      Timeout Circuitry
      0 = no timeout is occurring
      1 = timeout is occurring
      Note: Masters write to Register 0 to reset the fault circuitry after a fault
      has occurred and been resolved. Because Register 0 is Read-Only, no
      other functionality is affected.
