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.
External Interrupt Control register 2 (EICR2)
Reset value: 0000 0000 (00h)
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.
IS4[1:0] = 01 is the only safe configuration to avoid spurious interrupt in Halt and AWUFH
modes.
