      stmhal: Increase the priority of UART IRQ. · c8437f97
      Dave Hylands authored
      The UARTs have no FIFOs, so if interrupts are disabled
      for more than a character time (10 usec at 1 Mbit/sec)
      then characters get dropped.
      
      The overhead for handling a UART ISR is about 0.5 usec,
      so even at baud rates of 1 Mbit/sec this only corresponds
      to about 5% of the CPU. Lower baud rates will have less
      of an impact.
