When this bit is set, it selects the from-mid-transition interrupt functionality for PSWITCH. When set, in
conjuction with ENIRQ_PSWITCH, it will set PSWITCH_IRQ when either a 01 to 11 or 01 to 00 transition
is detected on the PSWITCH comparators. When this bit is set, PSWITCH_IRQ_SRC and
POLARITY_PSWITCH have no effect.
Reserved.
Interrupt Status for 4P2_BO. Reset this bit by writing a one to the SCT clear address space and not by a
general write.
Enable interrupt for 4P2_BO.
Interrupt Status for VDD5V_DROOP. Reset this bit by writing a one to the SCT clear address space and
not by a general write.
Enable interrupt for VDD5V_DROOP.
Interrupt status for PSWITCH signals. Interrupt polarity is set using POLARITY_PSWITCH. Comparator bit
is selected through PSWITCH_IRQ_SRC. Reset this bit by writing a one to the SCT clear address space
and not by a general write.
Set to 1 to use HW_POWER_STS_PSWITCH bit 1 as source, 0 for HW_POWER_STS_PSWITCH bit 0
