The DS320PR1601 has 5-level inputs pins that are used to control the configuration of the device. These 5-level inputs use a resistor divider (internal pull-up and external pull-down resistor) to help set the 5 valid levels and provide a wider range of control settings. External resistors must be of 10% tolerance or better. The pins are sampled at power-up only. Table 7-3 lists the pull-down resistor values to set the control logic levels for all 5-level control pins except MODE pin. For MODE pin refer to pin definition.
