Sub oscillator

2.7 Recommended connection of unused pins

If a pin is not used, it is recommended to connect it as follows:

• output pins: leave open

• input pins: connect to V

If no sub oscillator crystal is connected, connect XT1 to V

If the overall maximum output current of a concerned pin group exceeds its

maximum value the output buffer can be damaged. We recommend the

placement of a series resistor to prevent damage in case of accidentally

enabled outputs. Refer to the absolute maximum rating parameter in the

Electrical Target Specification.
