This pin is the analog current reference for the
integrated transceiver core. A 2.74 kΩ ± 1%
resistor should be tied from the RTRIM pad to
either the RXVDD0 or the RXVDD1 pin.
This pin is asserted LOW when a selective
reset is received that is targeted to one of this
device's aliases. This pin is asserted for 1–2 ms
after the last LIPr is received.
This active-LOW pin indicates that an electrical
fault has been detected by the channel0 PHY
device/module and, if the module has a laser,
the laser has been turned off. This pin causes
no interrupt or other reaction. It is assumed that
a Link Failure will occur and the register bit
reporting this pin's value will be used to
diagnose the problem.

Output Disable, Channel0. This output when
asserted disables an external GBIC or MIA
transmitter for channel0. This output is also
used to clear a module fault.
