Command or Query.
Sets or returns the external reference mute state in the form x, where:
0=Disable
1=Enable (SEE NOTE)
NOTE: To enable this command, the internal reference oscillator option must be
installed; otherwise, a mode error will result. A hardware mute condition generated
by the XRM mute is one of the conditions that can cause the MUT command to
return MUT=2. When enabled, the unit mutes when an external reference
oscillator is not detected.
