7.4 Device Functional Modes
7.4.1 Configuration Select (MODE_SEL)
Configuration of the device may be done via the MODE_SEL input pin, or via the configuration register bit. A pull-
up resistor and a pull-down resistor of suggested values may be used to set the voltage ratio of the MODE_SEL
input (V_R4) and V_DD33 to select one of the other 10 possible selected modes. See Figure 15 and Table 4.
