1. I/O pins used simultaneously for high current source/sink must be uniformly spaced around the package. In addition, the

total driven current must respect the absolute maximum ratings (see Section 10.2: Absolute maximum ratings).

2. When the MCU is in Halt/Active-halt mode, PA1 is automatically configured in input weak pull-up and cannot be used for

waking up the device. In this mode, the output state of PA1 is not driven. It is recommended to use PA1 only in input mode

if Halt/Active-halt is used in the application.

3. In the open-drain output column, ‘T’ defines a true open-drain I/O (P-buffer, weak pull-up, and protection diode to VDD are

not implemented).

4. The PD1 pin is in input pull-up during the reset phase and after internal reset release.
