Declare and pre-format the trickle charge mask byte according the constants defined in the application program. Trickle charging of the backup battery will only be active with rtc_diode value 1 or 2, and rtc_resistor value 2, 4 or 8. Any other combination will result in no trickle charging, without warning!
