1
External Interrupt Control register (EICR)
Reset value: 0000 0000 (00h)
Bits 7:6 = Reserved, must be kept cleared.
Bits 5:4 = IS2[1:0] ei2 sensitivity bits
Bits 3:2 = IS1[1:0] ei1 sensitivity bits
Bits 1:0 = IS0[1:0] ei0 sensitivity bits
These 8 bits can be written only when the I bit in the CC register is set.
Changing the sensitivity of a particular external interrupt clears this pending interrupt. This
can be used to clear unwanted pending interrupts. Refer to
function.
