According to EIEDGE, External interrupt polarity register has a
different means. If EIEDGE is level type, external interrupt polarity is
able to have Low/High level value. If EIEGDE is edge type, external
interrupt polarity is able to have rising/ falling edge value.
Level case:
0
When High level, Interrupt occurred (default)
1
When Low level, Interrupt occurred
Edge case:
0
When Rising edge, Interrupt occurred (default)
1
When Falling edge, Interrupt occurred
