Bit Description CAN : 1... HS-CAN interface is reason for interrupt
LIN : 1... At least one of the LIN interfaces is reason for interrupt
WAKE : 1... Wake up event is reason for interrupt
VDDx : 1... Under voltage condition is reason for interrupt
OTWARN : 1... Over temperature warning level crossing is reason for interrupt
OT : 1... Over temperature shutdown level crossing is reason for interrupt
FSM/SPI : 1... FSM or SPI are reasons for interrupt

Bit Description VDD2 ON : 1..Linear voltage regulator VDD2 enabled
0..Linear voltage regulator VDD2 disabled
VDD2 ENA PAD : 1..ENVDD2 set to logic level 1
0..ENVDD2 set to logic level 0
VDD2OC : 1..VDD2 over current detected
0..VDD2 over current not detected
VDD2 UV : 1.. VDD2 under voltage detected
0.. VDD2 under voltage not detected
VDDCAN UV : 1.. VDDCAN under voltage detected. If CAN is not activated, this bit is high
without generating a interrupt in this case.
0.. VDDCAN under voltage not detected
VDD1 UV : 1.. VDD1 under voltage detected
0.. VDD1 under voltage not detected
