Pin Description: Signal Descriptions by Group (Continued)
KSZ9692PB, KSZ9692PB-S
Pin Number
D9
Pin Name
FRAMEN
Pin Type
I/O
Pin Description
PCI Bus Frame signal, asserted Low.
FRAMEN is an indication of an active PCI bus cycle. It is asserted at the
beginning of a PCI transaction, i.e. the address phase, and de-asserted before
the final transfer of the data phase of the transaction.
B8
IRDYN
I/O
PCI Initiator Ready signal, asserted Low.
This signal is asserted by a PCI master to indicate a valid data phase on the
PAD bus during data phases of a write transaction. In a read transaction, it
indicates that the master is ready to accept data from the target. A target will
monitor the IRDYN signal when a data phase is completed on any rising edge
of the PCI clock when both IRDYN and TRDYN are asserted. Wait cycles are
inserted until both IRDYN and TRDYN are asserted together.
E9
TRDYN
I/O
PCI Target Ready signal, asserted Low.
This signal is asserted by a PCI slave to indicate a valid data phase on the
PAD bus during data phases of a read transaction. In a write transaction, it
indicates that the slave is ready to accept data from the target. A PCI initiator
will monitor the TRDYN signal when a data phase is completed on any rising
edge of the PCI clock when both IRDYN and TRDYN are asserted. Wait cycles
are inserted until both IRDYN and TRDYN are asserted together.
A9
DEVSELN
I/O
PCI Device Select signal, asserted Low.
This signal is asserted when the KSZ9692PB, KSZ9692PB-S is selected as a
target during a bus transaction. When the KSZ9692PB, KSZ9692PB-S is the
initiator of the current bus access, it expects the target to assert DEVSELN
within 5 PCI bus cycles, confirming the access. If the target does not assert
DEVSELN within the required bus cycles, the KSZ9692PB, KSZ9692PB-S
aborts the bus cycle. As a target, the KSZ9692PB, KSZ9692PB-S asserts this
signal in a medium speed decode timing. (2 bus cycle)
B7
IDSEL
I
Initialization Device Select. It is used as a chip select during configuration read
and write transactions.
B9
STOPN
I/O
PCI Stop signal, asserted Low.
This signal is asserted by the PCI target to indicate to the bus master that it is
terminating the current transaction. The KSZ9692PB, KSZ9692PB-S responds
to the assertion of STOPN when it is the bus master, either to disconnect, retry,
or abort.
A10
PERRN
I/O
PCI Parity Error signal, asserted Low.
The KSZ9692PB, KSZ9692PB-S asserts PERRN when it checks and detects a
bus parity error. When it generates the PAR output, the KSZ9692PB,
KSZ9692PB-S monitors for any reported parity error on PERRN.
When the KSZ9692PB, KSZ9692PB-S is the bus master and a parity error is
detected, the KSZ9692PB, KSZ9692PB-S sets error bits on the control status
registers. It completes the current data burst transaction, then stop the
operation. After the Host clears the system error, the KSZ9692PB,
KSZ9692PB-S continues its operation.
C9
SERRN
O
(open drain)
PCI System Error signal, asserted Low.
If an address parity error is detected, the KSZ9692PB, KSZ9692PB-S asserts
the SERRN signal two clocks after the failing address.
C4
M66EN
I
PCI 66MHz Enable
When asserted, this signal indicates the PCI Bus segment is operating at
66MHz.
This pin is mainly used in Guest bridge mode when the PCLK is driven by the
Host bridge.
