Rev 1.3, 2009/10/19

4.2 PA3-6, PB0-1, PD0-7

These pins are almost the same as PA0-2, except they do not support pseudo-open-drain mode. They
can be used in pure

open-drain

mode, instead.

4.3 PA7

PA7 can be only used in Schmitt-trigger input mode. The pull-up resistor is always connected to this pin.
