External Interrupt Polarity Register
| EXTPOLAR0 | External interrupt polarity for EINT0. 0 (LOW_ACTIVE_OR_FALLIN): Low-active or falling-edge sensitive (depending on EXTMODE0). 1 (HIGH_ACTIVE_OR_RISIN): High-active or rising-edge sensitive (depending on EXTMODE0). |
| EXTPOLAR1 | External interrupt polarity for EINT1. 0 (LOW_ACTIVE_OR_FALLIN): Low-active or falling-edge sensitive (depending on EXTMODE1). 1 (HIGH_ACTIVE_OR_RISIN): High-active or rising-edge sensitive (depending on EXTMODE1). |
| EXTPOLAR2 | External interrupt polarity for EINT2. 0 (LOW_ACTIVE_OR_FALLIN): Low-active or falling-edge sensitive (depending on EXTMODE2). 1 (HIGH_ACTIVE_OR_RISIN): High-active or rising-edge sensitive (depending on EXTMODE2). |
| EXTPOLAR3 | External interrupt polarity for EINT3. 0 (LOW_ACTIVE_OR_FALLIN): Low-active or falling-edge sensitive (depending on EXTMODE3). 1 (HIGH_ACTIVE_OR_RISIN): High-active or rising-edge sensitive (depending on EXTMODE3). |
