AM3354: AM335x internal pull-up/ pull-down resistors resistance

Hello Lukasz Przenioslo

Thank you for the query.

Please refer below section in the data sheet.

We have an FAQ that lists the links to key collaterals.

There is no actual internal PD resistor. Instead there are weak FETs that pull the signal high or low, typically to control a floating input with no trace routed from the pin.

Reading the SPRS717F doc I cannot find the resistance value of the internal GPIO pull-up resistors (and pull-down, if possible to configure for a GPIO).

So when internal pull-up is configured for an input, what values does it have?

Hi and thank you for the answer,

So, if I understand this correctly, there is a pull up/ down like circuitry that can provide/ sink up to around 200uA current?
