2. The followings Reference frequency can be selected through the combination the conditions of pin 3

(RDSW) and pin 28 (REFSW).

When the pin 28 is connected to GND directly, the pin 28 is state of DCGND.

When the pin 28 is connected to GND through decoupling capacitor, the pin 28 is state of ACGND.
