Address
The register addresses are presented in the
Hexa-
decimal
format.
Type:
The Command Registers are either Read-Only (RO)
type of registers or Read/Write (R/W) type of regis-
ters. Each channel of the XRT73L04A has eight
command registers, CR0-(n) through CR7-(n) where
(n) = 0, 1, 2 or 3. The associated addresses for each
channel are presented in , (repeated as Table 7).
N
OTE
:
The default value for each of the bit-fields within
these register is "0".

Command Register - CR0-(n)
The bit-format and default values for Command Reg-
ister CR0-(n) are listed below followed by the function
of each of these bit-fields.
COMMAND REGISTER CR0-(n)
Bit D4 - RLOL_(n) (Receive Loss of Lock Status -
Channel(n))
This Read-Only bit-field reflects the lock status of the
Channel(n) Clock Recovery Phase-Locked-Loop
This bit-field is set to “0” if the Channel(n) Clock Re-
covery PLL is in lock with the incoming line signal.
This bit-field is set to "1" if the Clock Recovery PLL is
out of lock with the incoming line signal.
Bit D3 - RLOS_(n) (Receive Loss of Signal Status -
Channel(n))
This Read-Only bit-field indicates whether or not the
Channel(n) of the Receiver is currently declaring an
LOS (Loss of Signal) Condition.
This bit-field is set to "0" if Channel(n) is not currently
declaring the LOS Condition.
This bit-field is set to "1" if Channel(n) is declaring an
LOS Condition.
Bit D2 - ALOS_(n) (Analog Loss of Signal Status -
Channel(n))
This Read-Only bit-field indicates whether or not the
Channel(n) Analog LOS Detector is currently declar-
ing an LOS condition.
This bit-field is set to "0" if the Analog LOS Detector
within Channel(n) is NOT currently declaring an LOS
condition. This bit-field is set to "1" if the Analog LOS
Detector is currently declaring an LOS condition.
N
OTE
:
The purpose is to isolate the Detector (e.g., either
the Analog LOS or the Digital LOS detector) that is declar-
ing the LOS condition. This feature may be useful for trou-
bleshooting/debugging purposes
Bit D1 - DLOS_(n) (Digital Loss of Signal Status -
Channel(n))
This Read-Only bit-field indicates whether or not the
Channel(n) Digital LOS Detector is currently declar-
ing an LOS condition.
This bit-field is set to "0" if the Channel(n) Digital LOS
Detector is NOT currently declaring an LOS condi-
