TMODE Tone Mode. Selects between the use of an external 22 kHz logic signal or the use of
the internal 22 kHz oscillator to control the tone generation on the LNB output. A 0
selects the external tone and a 1 selects the internal tone. See the Tone Generation
section for more information
TGATE Tone Gate. Allows either the internal or external 22 kHz tone signals to be gated,
unless the EXTM is selected for gating. When set to 0, the selected tone (via
TMODE) is off. When set to 1, the selected tone is on. See Tone Generation Section
for more information.
