Oscillator Pin 2 Control Dip Switch (Pin_2_Ctrl) - Silicon Laboratories Si5 UC-EVB Series Manual

5.2 Oscillator Pin 2 Control DIP Switch (Pin_2_Ctrl)

This DIP switch allows oscillator pin 2 to be driven from 1 of 3 sources.
1. High (VDD) level
2. Low (GND) level
3. I2C bus SCL signal
Note: The 3 signal sources listed above are located on separate pins on the left side of the switch and all pins on the right side are tied
together (common) and then connect to pin 2 of the oscillator. This means that only one (1) of the switches in this DIP switch bank
can be in the ON position at a time. Switching more than 1 switch to the ON position at a time may cause undesired behavior. All
switches set to OFF position effectively isolates pin 2 from any signal source and is the No Connect (NC) state.
To determine the required Pin 2 switch settings for your specific device, please refer to the Supported Device Tables in Chapter
