EXIxES bit description
Function
00 = Fast external interrupts disabled: Standard mode.
EXxIN pin not taken in account for entering/exiting Power Down mode.
01 = Interrupt on positive edge (rising).
Enter Power Down mode if EXiIN = ‘0’, exit if EXxIN = ‘1’ (referred as "high" active
level)
10 = Interrupt on negative edge (falling).
Enter Power Down mode if EXiIN = ‘1’, exit if EXxIN = ‘0’ (referred as “low” active
level)
11 = Interrupt on any edge (rising or falling).
Always enter Power Down mode, exit if EXxIN level changed.
