4.13 32K/DR_INT signal
The default 32K/DR_INT function is wake up interrupting input. The module is able to wake up from Standby and
Backup modes to Full Power mode when the signal is toggled by low-high-low state with >10 ms pulse length.
While in the DR_INT function the input is pulled low with an internal pull down resistor and the input can be left
floating (not connected).
Optionally the signal can be configured to 32768 Hz RTC clock signal output with a custom firmware. The
32K/DR_INT signal has CMOS 1.2V logic levels and when input, the signal is +3.6V tolerable.
