GPIO pull up timinghttps://devzone.nordicsemi.com/f/nordic-q-a/124949/gpio-pull-up-timingHi, We are testing a custom board based on the nRF5340 that drives an RGB LED strip using the TI TLC5947 LED driver. The TLC5947 has an OE (Blank) pin that disables/enables the outputs. When the system powers up, the LEDs briefly flash before theen-USTelligent Community 13Tue, 14 Oct 2025 10:03:17 GMTRE: GPIO pull up timinghttps://devzone.nordicsemi.com/thread/551392?ContentTypeID=1Tue, 14 Oct 2025 10:03:17 GMT137ad170-7792-4731-bb38-c0d22fbe4515:735c372e-c8ed-4446-8d3a-b19135e1d952Vidar Berg<p>Hello,</p> <p>Does the &quot;glitch&quot;&nbsp; happen during the initialization in&nbsp;tlc5947_init()? Since all the pins are outputs, I don’t see any reason to enable the pull-ups or pull-downs. The active high outputs initialized with the GPIO_OUTPUT_INACTIVE flag should&nbsp;be configured as output low and ensure that the signal is driven low. Are the pads accessible so you can probe the signals with a scope or logic analyzer?&nbsp;</p> <p>Best regards,</p> <p>Vidar</p><div style="clear:both;"></div>
