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
Sub oscillator If no sub oscillator crystal is connected, connect XT1 to V
connection
open.
Note 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.
