External interrupt control register 1 (EICR1)
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 “External interrupt function” on
page 61.
Whatever the sensitivity configuration, ei2 cannot exit the MCU from Halt, Active-Halt and
AWUFH modes when a falling edge occurs.
