Bit 7 PWRFAILZ:

0 = indicates that the PWRFAIL_SNS input voltage is above the 1-V threshold.

1 = indicates that the PWRFAIL_SNS input voltage is below the 1-V threshold.

Bit 6 LOWBATTZ:

0 = indicates that the LOWBATT_SNS input voltage is above the 1-V threshold.

1 = indicates that the LOWBATT_SNS input voltage is below the 1-V threshold.

Bit 5 PGOODZ VDCDC1:

0 = indicates that the VDCDC1 converter output voltage is within its nominal range. This bit is zero if

the VDCDC1 converter is disabled.

1 = indicates that the VDCDC1 converter output voltage is below its target regulation voltage

Bit 4 PGOODZ VDCDC2:

0 = indicates that the VDCDC2 converter output voltage is within its nominal range. This bit is zero if

the VDCDC2 converter is disabled.

1 = indicates that the VDCDC2 converter output voltage is below its target regulation voltage

Bit 3 PGOODZ VDCDC3: .

0 = indicates that the VDCDC3 converter output voltage is within its nominal range. This bit is zero if

the VDCDC3 converter is disabled and during a DVM controlled output voltage transition

1 = indicates that the VDCDC3 converter output voltage is below its target regulation voltage

Bit 2 PGOODZ LDO2:

0 = indicates that the LDO2 output voltage is within its nominal range. This bit is zero if LDO2 is

disabled.

1 = indicates that LDO2 output voltage is below its target regulation voltage

Bit 1 PGOODZ LDO1

0 = indicates that the LDO1 output voltage is within its nominal range. This bit is zero if LDO1 is

disabled.

1 = indicates that the LDO1 output voltage is below its target regulation voltage
