if we have a gp configured to work with rissing and falling edge, we
need to now wich edge active the interruption



On the 56F8357, you can not configure GPIO to interrupt on _either_ edge:
you have to specify which one you want to trigger the interrupt, rising or
falling.

Freescale tech support pointed out a way to detect _either_ edge: use a
counter/timer pin instead, because you can Configure those to count on
"either edge".
