So if you go for the internal setup there won&#39;t be any difference in choosing pullup or pulldown. Seeing as you will be able to decide these resistors yourself if you go for the external set-up, you will likely be able to achieve a lower current consumption this way, however the internal setup is energy efficient enough for most applications. In the end a well set up external will cause a lower current consumption increase, and choosing pull up or down is entirely up to you as it should not have any impact on the current consumption.</p> <p>Best regards</p> <p>Simon</p><div style="clear:both;"></div>
