[FONT=Arial]Sorry if I'm being dense, but I cannot find the range of values for the built-in pull-up or pull-down resistors on GPIO ports. All the diagrams (user manual and datasheet) just say "weak". I need to know the actual range of values.
Thanks in advance, Best Regards, Dave

PS: This to ensure external ESD-suppression components are sized such that the port still works as an input...

PPS: Input current graph seems to imply min 50ua for Vin < 1v, or equivalent of ~66k for 3.3v supply ? Is this the only spec ? Graph is "Fig 16. Typical pull-up current Ipu versus input voltage VI"
