INTERRUPTS (Cont’d)
EXTERNAL INTERRUPT CONTROL REGISTER
1 (EICR1)
Read/Write
Reset Value: 0000 0000 (00h)
Bits 7:6 = Reserved
Bits 5:4 = IS2[1:0] ei2 sensitivity
These bits define the interrupt sensitivity for ei2
according to Table 8.
Bits 3:2 = IS1[1:0] ei1 sensitivity
These bits define the interrupt sensitivity for ei1
according to Table 8.
Bits 1:0 = IS0[1:0] ei0 sensitivity
These bits define the interrupt sensitivity for ei0
according to Table 8.
Notes:
1. These 8 bits can be written only when the I bit in
the CC register is set.
2. Changing the sensitivity of a particular external
interrupt clears this pending interrupt. This can be
used to clear unwanted pending interrupts. Refer
to section “External interrupt function” on page 41.
EXTERNAL INTERRUPT CONTROL REGISTER
2 (EICR2)
Read/Write
Reset Value: 0000 0000 (00h)
Bits 7:4 = Reserved
Bits 3:2 = IS4[1:0] ei4 sensitivity
These bits define the interrupt sensitivity for ei1
according to Table 8.
Bits 1:0 = IS3[1:0] ei3 sensitivity
These bits define the interrupt sensitivity for ei0
according to Table 8.
Notes:
1. These 8 bits can be written only when the I bit in
the CC register is set.
2. Changing the sensitivity of a particular external
interrupt clears this pending interrupt. This can be
used to clear unwanted pending interrupts. Refer
to section “External interrupt function” on page 41.
3. IS4[1:0] = 01 is the only safe configuration to
avoid spurious interrupt in HALT and AWUFH
modes.
