DP83869HM: 100BASE-Tx interface and connection of not used signals for 1000Base-T

Part Number: DP83869HM


Hello,

I am wondering if there is osme recomendation connection of differentila signal C,D which are used for 1000Base-T and are not used for 100Base-Tx interface? Whall ve keed those signals flowting or groundedm over some resistor?
