WebHi 🙂. So I keep reading everywhere that leaving a CMOS input pin floating is bad because it is high impedance, can oscillate, etc. I understand and agree. But while a MCU is starting up (or when you're programming it) all its pin are in input state until the program has started to set them as output or add an internal pull-up.

Firstly, a floating Input is really only "dangerous" if the environment is noisy AND it is tied to an IRQ or similar (in most cases). If it isn't tied to internal hardware / IRQs, then it can't do much "damage". It's just NOT good "practice" to leave Inputs floating. It is not that simple.
