OUTHS_OL

Open-load

1: Indicates an open-load condition was detected at OUTHS output

Bit is latched until a “read and clear” command

OUTHS_OC

Overcurrent

1: Indicates an overcurrent condition was detected at OUTHS output

Bit is latched until a “read and clear” command

BOOST_IN_LP

Boost switched on in low power mode

1: Occurred

BYPASS_VDSMON_ERROR

BYPASS Vds monitoring error

1: Error is detected

0: No error reported

BOOST_VDSMON_ERROR

BOOST Vds monitoring error

1: Error is detected

0: No error reported

FBB_OV

FBB overvoltage

1: Indicates the voltage at FBB increased above the FBB overvoltage threshold

In ACTIVE and REC-1 modes, an interrupt pulse is generated at IRQ

Bit is latched until a “read and clear” command

FBB_UV

FBB under voltage

1: Indicates the voltage at FBB decreased below the FBB undervoltage threshold

In ACTIVE and REC-1 modes, an interrupt pulse is generated at IRQ

Bit is latched until a “read and clear” command
