Are the input bits from a pushbutton switch? If so, we need to debounce these inputs first. Do a search on keyboards and debounce.


If I am to understand what you want to do:

On the falling edge (1 -> 0) of an input bit, you want to output some data onto P1.

If the bit is held low for >5 seconds something is reset.

Each input bit outputs different data.


Where does the data to output come from? Is it a table?

How fast do we expect the input bits to change?

What happens if both bits go to 0 together? What data do we output?

Regardless of the number of inputs, the complexity doesn't increase but the amount of code does. De-compose your problem into simple steps first rather than worry about how to code it.
