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.
