Set to 1 to interupt when the interrupt source is high, 0 for low
Interrupt status for PSWITCH signal. Interrupt polarity is set using POLARITY_PWITCH and source selected
by PSWITCH_SRC.
Debug use only. Set to 1 to check for linear regulators ok. Set to 0 to check for 5V disconnected.
Interrupt Status for DC_OK. Reset this bit by writing a one to the SCT clear address space and not by a
general write.
Enable interrupt for DC_OK.
Interrupt Status for BATT_BO. Reset this bit by writing a one to the SCT clear address space and not by a
general write.
Enable interrupt for battery brownout.
Interrupt Status for VDDIO_BO. Reset this bit by writing a one to the SCT clear address space and not by
a general write.
Enable interrupt for VDDIO brownout.
Interrupt Status for VDDA_BO. Reset this bit by writing a one to the SCT clear address space and not by a
general write.
Enable interrupt for VDDIO brownout.
Interrupt Status for VDDD_BO. Reset this bit by writing a one to the SCT clear address space and not by a
general write.
Enable interrupt for VDDD brownout.
Set to 1 to check for 5V connected using VBUSVALID status bit. Set to 0 to check for 5V disconnected.
Interrupt status for VBUSVALID signal. Interrupt polarity is set using POLARITY_VBUSVALID. Reset this
bit by writing a one to the SCT clear address space and not by a general write.
Enable interrupt for 5V detect using VBUSVALID.
