VCXOD
Voltage Controlled External Oscillator Lock Detection
The VCXOD is used to indicate whether the internal clock refer-
ence is locked to an external VCO.
"0" = VCXO currently not Locked
"1" = VCXO Locked
NOTE: VCXOLKEN must be enabled for this bit to have functional
meaning.

LOSD
Loss of Signal Detection
The LOSD indicates the LOS activity.
"0" = No Alarm
"1" = A LOS condition is present
RO
0
D2
CDRD
Clock and Data Recovery Lock Detection
The CDRD is used to indicate that the CDR is locked.
"0" = CDR Out of Lock
"1" = CDR Locked

CMUD
Clock Multiplier Unit Lock Detection
The CMUD is used to indicate that the CMU is locked.
"0" = CMU Out of Lock
"1" = CMU Locked

FIFOD
FIFO Overflow Detection
The FIFOD indicates that the FIFO is experiencing an overflow
condition.
"0" = No Alarm
"1" = A FIFO Overflow condition is present
