Hi All,
I was going through the SPL2R04 Section SP28:SAS_TrainSEtup.
There is a statement in the State Description that the Transmitter Training=
 argument should be set to NO if  b) There is an active cable assembly atta=
ched to the phy.
We are trying to understand the reason behind this statement. Can you pleas=
e explain what would be the side effect of enabling transmitter training wi=
th an active cable assembly attached to the phy?.
