Address
The register addresses are presented in the
Hexa-
decimal
format.
Type:
The Command Registers are either Read-Only (RO)
or Read/Write (R/W) registers. Each channel of the
XRT73L02 has eight command registers, CR0-(n)
through CR7-(n) where (n) = 0 or 1. The associated
addresses for each channel is presented in Table 7.
N
OTE
:
The default value for each of the bit-fields in these
registers 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 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 in
the XRT73L02.
This bit-field is set to “0" if the Clock Recovery PLL is
in lock with the incoming line signal. This bit-field is
