(1)
The ILIM bit can only be set before the device enters operation (initial shutdown state).
(2)
The output node is internally pulled to ground. This mode is only possible for HC_SEL = L.
(3)
This mode of operation can only be activated for MODE_CTRL[1:0] = 01 and ENDCL = 0.

Power Good bit.
In write mode, this bit selects the functionality of the GPIO/PG output.
0: PG signal is routed to the GPIO port.
1: GPIO PORT VALUE bit is routed to the GPIO port.
In read mode, this bit indicates the output voltage conditions.
0: The converter is not operating within the voltage regulation limits.
1: The output voltage is within its nominal value.
