Connecting the _RESET-pin and _BM-pin to a separate GPIO

Do you see any problems (dead locks) connecting _RESET to a GPIO and _BM to another GPIO?

  • _RESET:
    • is intern connected to a pull up
    • the default for GPIO is input
    • I don't see any problems.
    • this is only used for backup. I know about the SW-Reset and watchDog.
  • _BM:
    • no pull up is used
    • two inputs are connected together
    • maybe an extern POR (cap to HIGH, high resistor to LOW) can help?
    • what happens during power on?
