Kevin O'Connor 116b304541 avr: Switch to input state prior to enabling pullup in gpio_in_reset() ... If switching a pin from output low to input with pullup, there is an intermediate state of either driven high or high impedance without a pullup. Similarly, when switching from output high to input without a pullup, there is an intermediate state of either driven low or high impedence with a pullup. In both cases it is preferable for the latter transition. Also, calculate the final setting prior to making any changes to reduce the time in that intermediate state.
