1) “1” = ON / enable, “0” = OFF / disable, OC = overcurrent, UV = undervoltage,
2) “1” = ON, “0” = OFF, OC = overcurrent, UV = undervoltage, OT = overtemperature (temp. shut-down)
3) Becomes valid after start-up time for voltage monitoring
4) Voltage monitoring not active in SBC Standby Mode
5) This bit needs to be read twice to indicate an undervoltage condition (only for
