Resolved! We are using STM32F429VET in our design. Please tell me if the internal structure of I/O port of STM32F429VET is the same.

Currently, we are testing whether smoke and fire will occur when adjacent I/O ports are shorted. If the internal structure is the same, we think that a representative set of tests is sufficient. However, if the internal structure is different, then a...
