When set, the signal is come from TI1- and TI1+ terminal to internal TG OP Amp
When reset, the signal is come from TI2- and TI2+ terminal to internal TG OP Amp
When set this bit, the TI2 input will provide high input impedance to meet application requirement.
When set, the signal TI2N will be connected to internal PO1 Amp.
When reset, the signal TI2N will be disconnected to internal PO1 Amp.
When set, the signal TI2N will be connected to internal PO2 Amp.
When reset, the signal TI2N will be disconnected to internal PO2 Amp.
The multiplexers of the TI Path Selection are shown in Figure 14-10.
