3 (NODIODE): Main power and backup power are connected without diode.
BUINACTPWRCON

Power Connection Configuration When Not in Backup Mode

0 (NONE): No connection.

1 (MAINBU): Main power and backup power are connected through a diode, allowing current to flow from main power source to backup power source, but not the other way.

2 (BUMAIN): Main power and backup power are connected through a diode, allowing current to flow from backup power source to main power source, but not the other way.
