MSP430FR5739: Quiescent Current in MSP430

Hello Abundis,
I think, I know the direction your question is pointing to, though it is a bit imprecise.
But let's assume, you're interested in the device current in reset state.
In reset state the MSP430 devices are forcing all GPIOs to default state, means input and GPIO function. All clocks are off, so no oscillators and clocks are active on chip, means CPU and modules are not clocked and again in default state, means off.
Now to the point of current consumption in this state.
What is active? All core modules are of course powered. This includes power management, memory, control register logic controlling the modules, BUS systems...
This means those modules, though not clocked are powered and thus consuming current, mainly due to leakages.
The other portion, which might be even the most significant, is the current, which can result from floating nodes. If e.g. a GPIO configured as input, and this is the default state, means also the state in reset, is not tied to either GND or supply voltage level, it will cause cross current through the input stages, dependent on the signal level, resulting from device and board leakages. The magnitude of such currents can reach 100µA as an order of magnitude. Keeping in mind all GPIOs are in input state, worst case the overall current consumption can be even in mA range, dependent on the external circuitry and conditions.
In reality floating GPIOs have usually the tendency to drift either to supply or GND level. That's why they are often overlooked, but later on with changed leakage conditions on the PCB causing trouble in the field.

Thanks a lot for your explanation Peter!
