TDET
Cable between LNB and the LNB head is disconnected. When cable disconnect test
mode is applied, the LNB linear regulator is disabled and a 1 mA current source is
applied between the BOOST and LNB output. If the LNB volts rise above 21 V,
CAD will be set to 1. The CAD bit is reset if the LNB volts drop below 19.95 V.
Not used.
Tone Detect. When tone is enabled by whatever option, or if a tone signal is re-
ceived from the LNB, TDET will be set to 1 if the tone appears at the LNB output.
When the tone is disabled and no tone is received from the LNB, TDET is reset.
