In the open-drain output column, "T" defines a true open-drain I/O (P-buffer, weak pull-up, and protection diode to V DD are not
The PD1 pin is in input pull-up during the reset phase and after internal reset release.
When the MCU is in Halt/Active-halt mode, PA1 is automatically configured in input weak pull-up and cannot be used for waking
I/O pins used simultaneously for high current source/sink must be uniformly spaced around the package. In addition, the total
