0 = Pin TDNn selects single rail mode or dual rail mode. (Default)
1 = Single rail mode enabled (with CRSn=0)
CODEn selects AMI or B8ZS/HDB3 encoder/decoder on a per channel basis with SINGn = 1 and CRSn = 0.
0 = B8ZS/HDB3 encoder/decoder enabled. (Default)
1 = AMI encoder/decoder enabled.
0 = Clock recovery enabled. (Default)
1 = Clock recovery disabled.
0 = Normal operation. (Default)
1 = Receiver n is powered down.
0 = Normal operation. (Default)
1 = Transmitter n is powered down
0 = Excessive zeros detect disabled. (Default)
1 = Excessive zeros detect enabled for B8ZS/HDB3 decoder in single rail mode.
0 = Code Violation Detect enable for B8ZS/HDB3 decoder in single rail mode. (Default)
1 = Code Violation Detect disabled.
0 = Normal operation. (Default)
1 = Equalizer in Receiver n is enabled, which can improve the receive performance when transmission length is more than
200 m.
(1)
(the corresponding transmit output driver enters a low power high-Z mode).
