RT1050 BOOT_CFG Pins

Hi, I'm doing a custom hardware design. I have read in the datasheet that the BOOT_CFG pins can't be left floating. Is it ok to connect them straight to GND or DCDC or do they need to go through a resistor? I'm not planning to use the pins for anything else other than BOOT_CFG

Thanks

Hi Martin,

As the BOOT_CFG pins are multiplexed with GPIOs, there is still an option of configuring them as output, causing a short circuit if the pads are directly connected to VDD/GND, that’s why it is recommended using external pull-up pull-down.


Hope this will be useful for you.
Best regards!
