LVTTL Output,
asynchronous
Link Fault Indication Output
. LFIx is an output status indicator signal. LFIx is the
logical OR of six internal conditions. LFIx is asserted LOW when any of the following
conditions is true:
Received serial data rate outside expected range
Analog amplitude below expected levels
Transition density lower than expected
Receive channel disabled
ULCx is LOW
Absence of REFCLKx±.
Device Configuration and Control Bus Signals
WREN
LVTTL input,
asynchronous,
internal pull-up
Control Write Enable
. The WREN input writes the values of the DATA[7:0] bus into
the latch specified by the address location on the ADDR[3:0] bus.
[5]
ADDR[3:0]
LVTTL input
asynchronous,
internal pull-up
Control Addressing Bus
. The ADDR[3:0] bus is the input address bus used to
configure the device. The WREN input writes the values of the DATA[7:0] bus into the
latch specified by the address location on the ADDR[3:0] bus.
[5]
Table 9 on page 20
lists the configuration latches within the device, and the initialization value of the
latches upon the assertion of RESET.
Table 10 on page 24
shows how the latches
are mapped in the device.
DATA[7:0]
LVTTL input
asynchronous,
internal pull-up
Control Data Bus
. The DATA[7:0] bus is the input data bus used to configure the
device. The WREN input writes the values of the DATA[7:0] bus into the latch
specified by address location on the ADDR[3:0] bus.

Table 9
lists the configuration
latches within the device, and the initialization value of the latches upon the assertion
of RESET.
Table 10
