you have to completely enroll to the thread from the first to the last answer there.

That thead started with a <<puzzle>> from Micahel Karas asking for

Sometimes an 8051/8051 microcontroller may need to monitor and debounce filter a multiple of inputs ...
http://www.8052.com/forum/read/57921

this is a clever way to debounce multiple inputs, but I prefer the more robust method of majority vote,
where every input is sampled for state and transition (timer based) and at a predefined number of samples (or a sliding window) the final status (state/transition) is determined by simple and strict rules according to the need of the application.
