Name:
Addresses:
Access:
• P0-P31: Rising Edge /High Level Interrupt Selection.
0 = No effect.
1 = The interrupt source is set to a Rising Edge detection or High Level detection event, depending on PIO_ELSR.

Name:
Addresses: 0x400E0ED8 (PIOA), 0x400E10D8 (PIOB), 0x400E12D8 (PIOC)
Access:
• P0-P31: Edge /Level Interrupt Source Selection.
0 = The interrupt source is a Falling Edge detection (if PIO_ELSR = 0) or Low Level detection event (if PIO_ELSR = 1).
1 = The interrupt source is a Rising Edge detection (if PIO_ELSR = 0) or High Level detection event (if PIO_ELSR = 1).
