        This trades an increase in power consumption for a decrease in GPIO pin
        read latency.

        If you enable this, a RTC tamper pin that has been configured as an
        interrupt can wake the CPU from Deep Sleep. Only RTC tamper pins
        (and the RTC alarm) can wake the CPU from Deep Sleep.

# TODO: this module is actually jus  t an artifact from the way periph_init_%
