GPIO pin of STM32F031G4U6 may be broken during connecting LSM6DSL.

[HUega.1]

I control LSM6DSL by using STM32F031G4U6.

INT2 of LSM6DSL connects PA8 of STM32F031G4U6.

PA8 of STM32F031G4U6 set output port, no pull-up, no-pull down.

I mistake the configuration of LSM6DSL.

I must set INT2 pin of LSM6DSL to input port, but I set it to output port.

So the current consumption of the circuit board increased.

When I don't use PA8, the current consumption is OK.

I think PA8 was broken.

Why was PA8 broken?

Vdd of STM32F031G4U6 and LSM6DSL is same.

Vdd is generated by the 3.3V regulator.

The INT2 pin should be an input on the MCU, not an output.
