14.5 RTC Bypass out
The VRTC pin brings out the Real Time Clock supply, which is separate from the rest of the
digital part, allowing having only RTC going on when all the other parts of the device are off.
To this power output a backup capacitor can be added in order to increase the RTC autonomy
during power off of the battery.
NO Devices must be powered from this pin.
14.6 VAUX Power Output
A regulated power supply output is provided in order to supply small devices from the module.
The signal is present on Pad R11 and it is in common with the PWRMON (module powered ON
indication) function.
This output is always active when the module is powered ON.
The operating range characteristics of the supply are:
