Hi Everyone,
1.) in 3.3V operating mode, I would like to know the typical value of the internal Pull-up/Pull-down resistor
According to the topic below, the value of the internal pull-down resistor is 20KΩ when there is no external resistor:
https://community.nxp.com/t5/i-MX-Processors/i-MX8M-Mini-pull-down-resistor-on-boot-pins/td-p/102643...
2.) According to ERR050080 in Errata IMX8MM_0N87W, "There is a degradation of the internal IO pullup/pulldown capability when the IO pads are continuously driven in the opposite logic level, for example, when internal pullup is enabled with external logic driving the pin low, and a 3.3V operating condition which limits the pads pullup/pulldown ability."
But when the PAD is driven at the same logic level, for example: when internal pullup is enabled with external logic driving the pin High, (Enable pin of another IC)
Is it possible to ignore degradation in this case?
Hope this helps,
Best regards,
Haryanl
