https://devzone.nordicsemi.com/f/nordic-q-a/94697/what-are-the-nrf52840-output-drive-modes-meanDear Support team I don&#39;t quite understand the part as the picture below after I read the specification, I would like to kown What are the output drive modes in the picture below mean and what they effect.en-USTelligent Community 13Fri, 09 Dec 2022 10:58:18 GMThttps://devzone.nordicsemi.com/thread/399890?ContentTypeID=1Fri, 09 Dec 2022 10:58:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8394a272-098e-4171-b4ce-00476c6a5c0bovrebekk<p>Hi Tom</p> <p>The drive setting allows you to individually control what a logical 0 or logical 1 should correspond to.&nbsp;</p> <p>Standard drive is the default mode, where the pin is able to sink our source a couple of milliamps.&nbsp;</p> <p>High drive allows you to sink/source a larger current, and is useful if you want to run high frequency signals over the pins (like a QSPI interface), or if you want to connect something to the pin that needs to draw more current.&nbsp;</p> <p>Disconnect simply means that the pin will be tri-stated (high impedance), which is useful for pins that are connected to a bus that is shared between multiple devices.&nbsp;<br />As an example, when using a pin for I2C it can be set in S0D1 mode, which means it will pull the pin low when you set the pin to 0, but will release the pin when you set it to 1, allowing other devices to communicate on the bus without being affected.&nbsp;</p> <p>For more information about what kind of currents you can sink or source in standard and high drive mode, please refer to the <a href="https://infocenter.nordicsemi.com/topic/ps_nrf52840/gpio.html?cp=4_0_0_5_8_2#unique_1104431930">GPIO electrical specification</a>.</p> <p>Best regards<br />Torbjørn&nbsp;</p><div style="clear:both;"></div>
