7.3.2.1 Four Level Input Pin (CSAGAIN)

Figure 7-8 shows the structure of the four level input pin, CSAGAIN, for hardware interface configuration. The input can be set with an external resistor. The CCSAGAIN is optional to help reduce the impact of GND noise. The CSA GAIN information is not latched at the device power up and may be updated during the device operation.
