Hi cjmjansen,

Can you explain your question with more detail?

All of the IO pins that are configurable GPIO's are configured by default as inputs with a pull-up while a reset is active-- and they will stay that way until you program them to do something else. There is a power-on reset that is generated internally in the chip, so the GPIO's will be in their default configuration (as above) when the chip is first powered on.
