Bit 5
MASK VDCDC3 and LDO1:
0 = indicates that the output voltage of either DCDC3 or LDO1 is within its nominal range. The
PGOOD output is not affected (not driven LOW)
1 = indicates that both LDO1 AND DCDC3 output voltage is below its target regulation voltage or
disabled. This will drive the PGOOD output low.
Bit 4..0
MASK VDCDC1/2/3, LDO1,2:
0 = the status of the power good Bit in Register PGOOD does not affect the status of the PGOOD
output pin
1 = the PGOOD pin is driven low in case the output voltage of the converter or LDO is below its
target regulation voltage or disabled.
