External Interrupt x Edge Selection Field (x=7...0)
0 0:
Fast external interrupts disabled: standard mode
EXxIN pin not taken in account for entering/exiting Power Down mode.
0 1:
Interrupt on positive edge (rising)
Enter Power Down mode if EXiIN = ‘0’, exit if EXxIN = ‘1’ (referred as ‘high’ active level)
1 0:
Interrupt on negative edge (falling)
Enter Power Down mode if EXiIN = ‘1’, exit if EXxIN = ‘0’ (referred as ‘low’ active level)
1 1:
Interrupt on any edge (rising or falling)
Always enter Power Down mode, exit if EXxIN level changed.
