What is the logic level of GPIO pins of STM32F429 during powering on?
I am using several GPIO pins as enable pins to enable downstream devices. These GPIOs must be "LOW" during power on until the firmware actively enables them.
I tried to find information from datasheet, but this information is not specified. My question is: when STM32F429 is being powered on and before the firmware takes care of GPIO configurations, what is the status of GPIO, HIGH, LOW or HIGH Z?
