Note that transmitter n is power down when either pin TCLKn is pulled to low or TPDNn is set to 1.
0 = Normal operation. (Default)
1 = Equalizer in Receiver n enabled, which can improved the receive performance when
transmission length is more than 200 m.
0 = Excessive zero detect disabled. (Default)

Line Code Selection.
CODEn selects AMI or B8ZS/HDB3 encoder/decoder on per-channel basis with SINGn = 1 and
CRSn = 0.
0 = B8ZS/HDB3 encoder/decoder enabled. (Default)
1 = AMI encoder/decoder enabled.
0 = Pin TDNn selects single rail mode or dual rail mode. (Default)
1 = Single rail mode enabled (with CRSn=0)
0 = Normal operation. (Default)
1 = Power down in receiver n.
0 = Clock recovery enabled. (Default)
1 = Clock recovery disabled.
