    GE/GC864-QUAD V2 and GE864-GPS Hardware User Guide 1vv0300915 Rev.5 – 2011-10-03 11.10. 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.
