6.1 Register Description
This is the detailed register description of each bit. Whenever the variable “
n
” in italics is used in any of the register
descriptions, it represents 1–16. Note that in the register descriptions, there are duplicate registers for LIUs 1–8
and LIUs 9–16. There are registers in LIUs 1–8 that do not have a duplicate in the register set for LIUs 9–16. For
these registers, only one address is listed. All other registers list two addresses, one for LIUs 1–8 and one for LIUs
9–16.
6.1.1 Primary Register Bank
The ADDP register must be set to 00h to access this bank.

Bits 7: Device CODE ID Bit 7 (ID7).
This bit is ‘one’ for long-haul operation.
Bits 6 to 3: Device CODE ID Bits 6 to 3 (ID6 to ID3).
These bits tell the user the number of ports the device
contains.
Bits 2 to 0: Device CODE ID Bits 2 to 0 (ID2 to ID0).
These bits tell the user the revision of the part. Contact the
factory for details.

Bit 7 to 0: Analog Loopback Control Bits Channel
n
(ALBC

).
When this bit is set, LIU
n
is placed in Analog
Loopback. TTIP and TRING are looped back to RTIP and RRING. The data at RTIP and RRING is ignored. LOS
Detector is still in operation. The jitter attenuator is in use if enabled for the Transmitter or Receiver.
