3.11.7 Battery Backup
The RTC section has an independent (RTC) Vcc power supply
pin. Operation can be continued in case of loss of Vcc (pins 36/
77), the main power supply, if an external battery backup is
connected to (RTC) Vcc.
The battery backup is activated by setting BUKEN = “0”
when loss of the main power supply, Vcc (pins 36/77), is
detected externally.
A minimum (RTC) Vcc voltage of 2V is guaranteed by the
battery backup.
Use a backup circuit that provides the same potential at
(RTC) Vcc found at Vcc (pins 36/77) when the main power
supply is on.
Figures 3.11 (7) and (8) below show battery backup circuit
configurations.
