This change is required to sucessfully use PA13/PA14 for UART. Otherwise they function as SWDIO/SWCLK. Relevant excerpt from the reference manual (translated): The initial state of PA13, PA14, PA15, PB3, and PB4 ports is that the JTAG/SWD function is valid after reset. When configuring FSEL[5:0] to select the function, you need to write 0 to the corresponding bit of the register PSPCR to invalidate the JTAG/SWD function.
