5FIFOS
FIFO Size Select:
Writing a "1" to this bit selects 64 bit FIFO depth.
Write "0" to select 32 bit FIFO depth.
R/W
0
4RxJA
Receive Jitter Attenuator:
Select: Writing a "1" to this bit selects jitter attenuator in the
receive path.
If bit 3(TxJA) is also set, jitter attenuator is disabled.
R/W
0
3TxJA
Transmit Jitter Attenuator Select:
Writing a "1" to this bit selects jitter attenuator in the transmit
path. If bit 4(RxJA) is also set, jitter attenuator is disabled.
R/W
0
2
RXMUTE
Receive Muting:
Writing a "1" to this bit mutes receive data output to a low state
during LOS condition to prevent data chattering.
R/W

EXLOS
Extended LOS:
Writing a "1" to this bit extends the number of zeros at the input
to 4096 bits, (approximately 2mS), before LOS is declared.
R/W
0
0ICT
In-Circuit-Testing:
Writing a "1" to this bit causes all output pins to be in high
impedance mode for in-circuit testing. The software ICT function
is equivalent to connecting pin 20 to ground.
R/W
0
NOTE: Register Type Abrbreviation:
R = Read Only, R/W = Read or Write, RUR = Reset Upon Read
