Changes made for Pathfinder 5226 controllers.

There was a bug in the I/O port handling section of the 5226 controller where it made interrupts unusable. For reference refer to:

SCN 4488 5226; I/O Port Handling Bug Fixes

The band-aid to get around this for most inputs were to make them polled instead of interrupts. One of these inputs to become polled was the Clamp Pressure Reached input. This made the clamp drive down further than needed to say the clamp reached pressure.

Making the Clamp Pressure Reached input an interrupt made the clamp stop much faster when trying to reach pressure on a system that had a pressure switch for the clamp.
