3.3.3 Set/Clear Operating Modes (M)
Operating modes of the LN-CSAC are enabled/disabled by individual bits in the mode
register. The !M command provides access to set/clear each of the bits independently.
The mode register is non-volatile; Settings persist across power cycles.
The unit responds by reporting the current value of the mode register in hexadecimal.
Each bit in the mode register is associated with enabling/disabling a particular operat-
ing mode. The bit assignments are shown in the following table.
Example: Enable and then Disable disciplining:
Command: !MD[CRLF]
Unit response: 0x0010[CRLF]
Command: !Md[CRLF]
Unit response: 0x0000[CRLF]
The current value of the mode register is returned in the standard telemetry query (see
Section 3.3.1 “Telemetry (6 and ^)”) or may be queried independently with the !M?
command.
Example: Query mode register:
Command: !M?[CRLF]
Response: 0x0010[CRLF]
Autosync mode and Discipline mode are mutually exclusive. Setting either Autosync or
Discipline disables the other.
Note: The frequency steering command (!F) is recommended for real-time disci-
plining of LN-CSACs, but the value should not be latched (!FL) on every
steer due to the physical limit on the number of times the non-volatile mem-
ory may be written before damage. For example, if a !FL command is
applied to the LN-CSAC at a rate of 1/sec, the LN-CSAC may experience
operational failure within a few days of operation
