3.10.4 Line Quality Monitor
It is possible to determine the amount of Equalization being
used by accessing certain test registers with the DSP
engine. This provides a crude indication of connected
cable length. This function allows for a quick and simple
verification of the line quality in that any significant
deviation from an expected register value (based on a
known cable length) would indicate that the signal quality
has deviated from the expected nominal case.
