NAME
Logic control input: see truth table
Logic output (open collector). Normally in HIGH
IMPEDANCE, goes LOW when current or thermal
overload occurs
In stand-by mode, the voltage on MI is routed to LNBA pin.
Can be left open if bypass function is not needed
See truth tables for voltage and port selection
