Protected Monitoring/Address Select Inputs.
Hardware Mode
In hardware mode these pins are used to select a specific port for non
intrusive monitoring. During protection monitoring receiver 0 inputs are
internally connected to a specific transmit or receive port. Receiver 0
routes the data from the selected port to its data and clock recovery
circuits. The data on the monitor port can be routed to TTIP0/TRING0 by
activating the remote loopback for channel 0 (TCLK0 must be active in
order for this operation to take place). In addition, the recovered clock and
data can be observed at the RCLK0/RPOS0/RNEG0 outputs.
If A0-A3 are Low, the LXT386 is configured as a quad line transceiver
without monitoring capability.
Transmitter monitoring is not supported when the respective channel is set
to analog loopback mode.
Host Mode
In non-multiplexed host mode, these pins function as non-multiplexed
address pins.
