If the mask is (unsigned)-1, it will not add any limit. This should be the default. The advantage of the mask is that you can speedup the keycode decoding by not calling a seek routine in the cases where it doesn't make sense. Also, the cost of scancode & scancode_mask is cheap enough, comparing with the potential optimization gain of not seeking a data in a table that wouldn't match anyway. Also, the IR core may automatically generate such mask, by doing an "and" operation of all the scancodes at the table during table initialization/changes. If the mask is zero, it defaults to use a (unsigned) -1 mask.
