EICR register description (continued)
Nested interrupts register map and reset values
Interrupt sensitivity (ei0 sensitivity)
Interrupt polarity (for port D)
The interrupt sensitivity, defined using the IS2[1:0] bits, is applied to the following
external interrupts:
External interrupt ei0 (port D[6:4]):
00: External interrupt sensitivity = falling edge and low level (IPA bit = 0)
01: External interrupt sensitivity = rising edge only (IPA bit = 0)
10: external interrupt sensitivity = falling edge only (IPA bit = 0)
11: external interrupt sensitivity = rising and falling edge (IPA bit = 0 and IPA bit = 1)
External interrupt ei0 (port D[3:1]):
00: External interrupt sensitivity = falling edge and low level
01: External interrupt sensitivity = rising edge only
10: External interrupt sensitivity = falling edge only
11: External interrupt sensitivity = rising and falling edge
These 2 bits can be written only when I1 and I0 of the CC register are both set to 1
(level 3).
This bit is used to invert the sensitivity of port D [6:4] external interrupts. It can be set
and cleared by software only when I1 and I0 of the CC register are both set to 1
(level 3).
0: No sensitivity inversion
1: Sensitivity inversion
