      In the Standby mode, the I/Os are by default in floating state. If the IORETEN bit in the
      PWR_IORETR register is set, the I/Os output state is retained. IO Retention mode is
      enabled for all IO except the IO support the standby functionality and JTAG IOs (PA13,
      PA14, PA15 and PB4). When entering into Standby mode, the state of the output is
      sampled, and pull-up or pull-down resistor are set to maintain the IO output during Standby
      mode.
      If the JTAGIORETEN bit in the PWR_IORETR register is set, the I/Os output state is
      retained. IO Retention mode is enabled for PA13, PA14, PA15 and PB4 (default JTAG pullup/
      pull-down after wakeup are not enabled).
