External 32 kHz input and internal 32 kHz output
The EXT32K input and the 32K_OUT output are available only on the SARA-G300 and SARA-G310
modules to provide the 32 kHz reference clock for the Real Time Clock (RTC) timing, used by the
module processor to reach the low power idle-mode and provide the RTC functions.
SARA-G350 and LISA-U modules are equipped with internal 32 kHz oscillator to provide the same
functions.
LISA-C2 series do not provide RTC and the relative functions.
