THE MICROPROCESSOR SERIAL INTER-
FACE
The on-chip Command Registers of the
XRT73LC00A DS3/E3/STS-1 Line Interface Unit IC
are accessed to configure the XRT73LC00A into a
variety of modes. This section describes the Com-
mand Registers and how to use the Microprocessor
Serial Interface.

EGISTERS
A listing of these Command Registers, their Address-
es and their Bit-Formats are listed in Table 5.
Address:
The register addresses are in
Hexadecimal
format.
Type:
The Command Registers are either Read-Only (RO)
or Read/Write (R/W) registers.
N
OTES
:
1. The default value for each of the bit-fields in these
registers is “0”.
2. If the REGRESET input pin is asserted, then the
contents of the command registers is reset to all
"0's" resulting in the XRT73LC00A operating in the
mode corresponding to the default values of the
Command Registers.
DESCRIPTION OF BIT-FIELDS FOR EACH COM-
MAND REGISTER
5.1.1
Bit D4 - RLOL (Receive Loss of Lock Status)
This Read-Only bit-field reflects the lock status of the
Clock Recovery Phase-Locked-Loop in the
XRT73LC00A.
This bit-field is set to “0” if the Clock Recovery 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 (Receive Loss of Signal Status)
This Read-Only bit-field indicates whether or not the
Receiver in the XRT73LC00A is currently declaring
an LOS (Loss of Signal) Condition.
This bit-field is set to “0” if the XRT73LC00A is not
currently declaring the LOS Condition. This bit-field
