Example of INT5 Digital Debounce Function (if P17DDR = "03
1. (Condition after reset). P17DDR=FF
2. Set the P17DDR register to "03
3. The P17DDR register will stops counting when the pin input level and the signal output level are matched (e.g., both levels are "H") while
4. If the pin input level (e.g.,"L") and the signal output level (e.g.,"H") are not matched the P17DDR register will start decrement again after the
5. When the P17DDR register is underflow, it stops counting and the signal output will output the same as pin input level (e.g."L").
6. If the pin input level (e.g.,"H") and the signal output level (e.g., "L") are not matched again, the P17DDR register will start decrement again
7. When the P17DDR register is underflow, it stops counting and the signal output will output the same as pin input level (e.g."H").
8. If the pin input level (e.g.,"H") and the signal output level (e.g., "L") are not matched again, the P17DDR register will start decrement again
