      STOPN
      I/O
      PCI Stop
      This signal is asserted low by the target device to request the master device to stop the
      current transaction.
      73
      IDSEL
      I/O
      PCI Initialization Device Select
      This signal is used to select the KSZ8841-PMQL during configuration read and write
      transactions. Active high.
      74
      DEVSELN
      I/O
      PCI Device Select
      This signal is asserted low when it is selected as a target during a bus transaction. As a
      bus master, the KSZ8841-PMQL samples this signal to insure that a PCI target
      recognizes the destination address for the data transfer.
      75
      REQN
      O
      PCI Bus Request
      The KSZ8841-PMQL will assert this signal low to request PCI bus master operation.
      76
      GNTN
      I
      PCI Bus Grant
      This signal is asserted low to indicate to the KSZ8841-PMQL that it has been granted
      the PCI bus master operation.
      77
      PERRN
      I/O
      PCI Parity Error
      The KSZ8841-PMQL as a master or target will assert this signal low to indicate a parity
      error on any incoming data. As a bus master, it will monitor this signal on all write
      operations.

      PCI System Error
      This system error signal is asserted low by the KSZ8841-PMQL. This signal is used to
      report address parity errors.

      Command and Byte Enable
      These signals are multiplexed on the same PCI pins. During the address phase, these
      lines define the bus command. During the data phase, these lines are used as Byte
      Enables, The Byte enables are valid for the entire data phase and determine which byte
      lanes carry meaningful data.
      89
      PAD31
      I/O
      PCI Address / Data 31
      Address and data are multiplexed on the all of the PAD pins. The PAD pins carry the
      physical address during the first clock cycle of a transaction, and carry data during the
      subsequent clock cycles.
