The debug pins are in AF pull-up/pull-down after reset:
PA14: SWCLK in pull-down
PA13: SWDIO in pull-up
When the pin is configured as output, the value written to the output data register
(GPIOx_ODR) is output on the I/O pin. It is po ssible to use the output driver in push-pull
mode or open-drain mode (only the low level is driven, high level is HI-Z).
