This is going to be an odd question, but those are the only kind I know how to ask....
Is the internal mechanism to enable or disable the internal pull-ups still available on PORT B.5?
I fully understand the following...
- B.5 has its own hard wired internal 50k pull-up.
- B.5 is enabled as a reset pin by default.
- I can set the reset disable fuse, and then require HV programming.
- I can use B.5 for ADC as long as it is held above 2v.
But I still want to know if the fabric still contains the internally switchable weak pull-up on B.5
I have a use for being able to toggle another 50k on top of the built in 50k pull-up if I can.
Consider that function to be "an extremely weak output".
So that's it, just wondering if anyone knows the answer.
