I need to use test points to apply external 3.3V to stimulate HW on my board. That signal is normally controlled by a GPIO setup as an output on the MSP432. But unfortunately I do not have control over the output for this test. So the question I have is: can I apply the external 3.3V to the test point without damaging the MSP432's GPIO configured as an output? There is no concern of driving too high of voltage. During the test, the MSP432 will not have control over the pin. I saw in the datasheet that all GPIOs are High Z by default, but not sure exactly how that applies in this situation with an assigned pin.
This is the way it has to be done due to the particular constraints on our design, so suggestions of doing it other ways is not what I am looking for. Just simply wondering if doing what is mentioned above is ok or will cause damage.
