Transmit Tip.
Transmit Ring.
These pins are differential line driver outputs. TTIP and TRING will be in
high impedance state if the TCLK pin is Low or the OE pin is Low. In
software mode, TTIP and TRING can be tristated on a port-by-port basis
by writing a
‘

’
to the OEx bit in the Output Enable Register (OER).
