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

Alternate function remapping
As shown in the rightmost column of the pin description table, some alternate functions can
be remapped at different I/O ports by programming one of eight AFR (alternate function
remap) option bits. When the remapping option is active, the default alternate function is no
longer available.
To use an alternate function, the corresponding peripheral must be enabled in the peripheral
registers.
Alternate function remapping does not effect GPIO capabilities of the I/O ports (see the GPIO
section of the family reference manual, RM0016).
