PRODUCTION DATA.
Configuration of the device may be done either through the MODE_SEL[1:0] input pins or through the configuration register bits. A pullup resistor and a pulldown resistor of suggested values may be used to set the voltage ratio of the MODE_SEL[1:0] inputs (VR4) and VDD33 to select one of the other eight possible selected modes. See Table 7 and Table 8. Possible configurations are shown in Figure 28 and Figure 29.
