25MHz crystal/oscillator clock connections
Pins (X1, X2) connect to a crystal. If an oscillator is used, X1 connects to a 3.3V
tolerant oscillator and X2 is no connected.
Note: Clock is
50ppm for both crystal and oscillator.

RSTN
Ipu
Hardware Reset, Active Low
RSTN will cause the KSZ8841-PMQL to reset all of its functional blocks. RSTN must be
asserted for a minimum duration of 10 ms.
68
PAR
I/O
PCI Parity
Even parity computed for PAD[31:0] and CBE[3:0]N, master drives PAR for address
and write data phase, target drives PAR for read data phase.
69
FRAMEN
I/O
PCI Cycle Frame
This signal is asserted low to indicate the beginning of the address phase of the bus
transaction and de-asserted before the final transfer of the data phase of the
transaction in a bus master mode. As a target, the device monitors this signal before
decoding the address to check if the current transaction is addressed to it.
70
IRDYN
I/O
PCI Initiator Ready
As a bus master, this signal is asserted low to indicate valid data phases on PAD[31:0]
during write data phases, indicates it is ready to accept data during read data phases.
As a target, it’ll monitor this IRDYN signal that indicates the master has put the data on
the bus.
71
TRDYN
I/O
PCI Target Ready
As a bus target, this signal is asserted low to indicate valid data phases on PAD[31:0]
during read data phases, indicates it is ready to accept data during write data phases.
As a master, it will monitor this TRDYN signal that indicates the target is ready for data
