Emulate slow rise time of IO port pin when transitioning from low output to input

Description

When an IO pin on one of the controller ports is set to an input, it will be pulled high by a pull up resistor. However, it appears that pull up is weak so the rise time is observable. Decap Attack has a buggy controller reading routine that depends on this behavior.
