The internal pullup resistors are not on the inputs in default mode are they?
Don't they need to be applied in a register?
I have a project where I want to twist some things around and hopefully make b0 - b7 and d0 - d4 inputs, all with pullups.
(Another problem? Only certain pins have the pullups?). (I know, I'll look at the datasheet).
So, if I set the pin to an input and apply the pullup, I should see the PS voltage (or close to it) at that pin, right?
THANKS.
