You'd have to look at the spec sheet, possibly very carefully, to determine if the clamping applies to the analog pins -- but it almost certainly does since it is usually the pad that performs this function and since, regardless of whether it is digital or analog I/O, the goal is to protect the chip from voltage above (or below) particular limits.hi,
I do want to ask if all the pins on microcontroller are digital i/o's?
Since in a spec of freesclae datasheet.
It was mentioned that all digital i/o's are clamped to 5V internally.Does it mean analog pins also clamped to 5V?
