Help to find in datasheet whic Pins number and pins decription are used as uart /spi/i2c/pwm/timer/ I2Shttps://devzone.nordicsemi.com/f/nordic-q-a/73979/help-to-find-in-datasheet-whic-pins-number-and-pins-decription-are-used-as-uart-spi-i2c-pwm-timer-i2sHello, All I go through datasheet of nRF5284o QFN73 IC. But i can&#39;t found which pins are used as uart /spi/i2c/pwm/timer/ I2S in pin description. Because pin assignment i can&#39;t found any description So, I request you that please help me that which GPIOen-USTelligent Community 13Wed, 14 Apr 2021 12:14:03 GMTRE: Help to find in datasheet whic Pins number and pins decription are used as uart /spi/i2c/pwm/timer/ I2Shttps://devzone.nordicsemi.com/thread/304804?ContentTypeID=1Wed, 14 Apr 2021 12:14:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ad1b0caa-8f61-4f9f-8c99-6693b66ba65bJ&#248;rgen Holmefjord<p>Hi,</p> <p>All nRF5x series ICs have a pin crossbar feature which allows you to use any GPIO with any serial peripheral. The GPIO pin numbers are normally set in the <a href="https://infocenter.nordicsemi.com/topic/ps_nrf52840/uarte.html#register.PSEL.TXD">PSEL registers</a> of the peripheral. Some pins are marked &quot;Standard drive, low frequency I/O only&quot; in the <a href="https://infocenter.nordicsemi.com/topic/ps_nrf52840/pin.html">Pin assignment</a> documentation, you should make sure to honor this when choosing pins for high-frequency peripherals.</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
