2.1 DS320PR410 5-Level I/O Control Inputs

Each DS320PR410 features 5-level input pins (MODE, GAIN, RX_DET, EQ0 / ADDR0, and EQ1 / ADDR1) that are used to control the configuration of the device. These 5-level inputs use a resistor divider to help set the four valid levels to provide a wider range of control settings.
