xxxx11xx Signals will pass through from Aux_Fnc to TV_Fnc or vice versa.
The voltage applied to this pin (when set as an input) sets the state of the
two LSBs of the read register. See the note*

* Function pin voltages: (I) in output mode, are defined by the two LSBs of register 2, (II) in input mode, set the
state of the two LSBs of the read register.
Digital read is not meaningful in the pass-through mode( xxxx11xx ).
** Aux_Cin is not available on the 48 QFN package option.
*** Not available in the 48 QFN package option.
