9.2. Indication of Software Ready
The SW_RDY signal provides indication about the ability of the module to receive commands
As long as the SW_RDY is asserted low it indicates that the LE910C1 has not yet finished booting
Once the SW_RDY is asserted high, it indicates that the LE910C1 is ready to receive commands
The SW_RDY does not have a dedicated pin
The SW_RDY functionality is available on GPIO_08 pin (by default GPIO_08 functions as SW_RDY
9.3. RTC – Real Time Clock
The RTC within the LE910C1 module does not have a dedicated RTC supply pin.
The RTC block is supplied by the VBATT supply.
If the battery is removed, RTC is not maintained so if maintaining an internal RTC is needed,
VBATT must be supplied continuously.
In Power OFF mode, the average current consumption is ~25uA.
9.4. VAUX Power Output
A regulated power supply output is provided to supply small devices from the module. This
output is active when the module is ON and goes OFF when the module is shut down. The
operating range characteristics of the supply are as follows:
