case, the R_TERM[1:0] bits (TERM, 03H) can be set to choose 75 Ω, 100
Ω, 110 Ω or 120 Ω internal impedance of RTIP/RRING. If R_TERM[2] is
set to ‘1’, the internal impedance matching circuit will be disabled. In this
case, the external impedance matching circuit will be used to realize the
impedance matching.
