Register description
External interrupt control register 0 (EICR0)
Read/Write
Reset value: 0000 0000 (00h)
Bits 7:6 = IS3[1:0] ei3 sensitivity
The interrupt sensitivity, defined using the IS3[1:0] bits, is applied to the ei3 external
interrupts:
Table 17.
These 2 bits can be written only when I1 and I0 of the CC register are both set to 1 (level 3).
Bits 5:4 = IS2[1:0] ei2 sensitivity
The interrupt sensitivity, defined using the IS2[1:0] bits, is applied to the ei2 external
interrupts:
Table 18.
These 2 bits can be written only when I1 and I0 of the CC register are both set to 1 (level 3).
Bits 3:2 = IS1[1:0] ei1 sensitivity
The interrupt sensitivity, defined using the IS1[1:0] bits, is applied to the ei1 external
interrupts:
Table 19.
