Please tell me about the GPIOs of MSP430.
Q1:If P3.0 suddenly changes from high to low, is it possible for P3.1 to be affected by the internal circuitry and thus change the state of the pins?
However, when S3 is set to ON, the waveform is "normalcy".
Even if C1, 2 and 3 are deleted and S6 is turned on, the waveform is "normalcy".
I suspect the layout on the "SW PCB" side, but I would like to confirm the effect on the MSP430 side.
If it is not the effect of MSP430, I would appreciate it if you could tell me other possible causes of the problem.
