External Interrupt Polarity Register
| EXTPOLAR0 | External interrupt 0 EINT0 polarity. 0 (FALLING_EDGE): Falling edge. EINT0 is low-active or falling-edge sensitive (depending on EXTMODE0). 1 (RISING_EDGE): Rising edge. EINT0 is high-active or rising-edge sensitive (depending on EXTMODE0). |
| EXTPOLAR1 | External interrupt 1 EINT1 polarity. 0 (FALLING_EDGE): Falling edge. EINT1 is low-active or falling-edge sensitive (depending on EXTMODE1). 1 (RISING_EDGE): Rising edge. EINT1 is high-active or rising-edge sensitive (depending on EXTMODE1). |
| EXTPOLAR2 | External interrupt 2 EINT2 polarity. 0 (FALLING_EDGE): Falling edge. EINT2 is low-active or falling-edge sensitive (depending on EXTMODE2). 1 (RISING_EDGE): Rising edge. EINT2 is high-active or rising-edge sensitive (depending on EXTMODE2). |
| EXTPOLAR3 | External interrupt 3 EINT3 polarity. 0 (FALLING_EDGE): Falling edge. EINT3 is low-active or falling-edge sensitive (depending on EXTMODE3). 1 (RISING_EDGE): Rising edge. EINT3 is high-active or rising-edge sensitive (depending on EXTMODE3). |
| RESERVED | Reserved, user software should not write ones to reserved bits. The value read from a reserved bit is not defined. |
