e-SING: Single Rail Mode Setting Register (R/W, Expanded Address = 00H)
Symbol
Position
Default
Description
SING[7:0]
SING.7-0
00H
0 = Pin TDNn selects single rail mode or dual rail mode. (Default)

e-CODE: Encoder/Decoder Selection Register (R/W, Expanded Address = 01H)
Symbol
Position
Default
Description
CODE[7:0]
CODE.7-0
00H
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.
e-CRS: Clock Recovery Enable/Disable Selection Register (R/W, Expanded Address = 02H)
Symbol
Position
Default
Description
CRS[7:0]
CRS.7-0
00H
0 = Clock recovery enabled. (Default)
1 = Clock recovery disabled.
e-RPDN: Receiver n Powerdown Register (R/W, Expanded Address = 03H)
Symbol
Position
Default
Description
RPDN[7:0]
RPDN.7-0
00H
0 = Normal operation. (Default)
1 = Receiver n is powered down.
e-TPDN: Transmitter n Powerdown Register (R/W, Expanded Address = 04H)
Symbol
Position
Default
Description
TPDN[7:0]
TPDN.7-0
00H
0 = Normal operation. (Default)
1 = Transmitter n is powered down(1) (the corresponding transmit output driver enters a low power high-Z mode).
1. Transmitter n is powered down when either pin TCLKn is pulled low or TPDNn is set to ‘1’
e-CZER: Consecutive Zero Detect Enable/Disable Register (R/W, Expanded Address = 05H)
Symbol
Position
Default
Description
CZER[7:0]
CZER.7-0
00H
0 = Excessive zeros detect disabled. (Default)
1 = Excessive zeros detect enabled for B8ZS/HDB3 decoder in single rail mode.
e-CODV: Code Violation Detect Enable/Disable Register (R/W, Expanded Address = 06H)
Symbol
Position
Default
Description
CODV[7:0]
CODV.7-0
00H
0 = Code Violation Detect enable for B8ZS/HDB3 decoder in single rail mode. (Default)
1 = Code Violation Detect disabled.
