INTERRUPTS (Cont’d)
EXTERNAL INTERRUPT CONTROL REGISTER
(EICR)
Read/Write
Reset Value: 0000 0000 (00h)
Bit 7:6 = IS3[1:0] ei3 sensitivity
These bits define the interrupt sensitivity for ei3
(Port B0) according to Table 6.
Bit 5:4 = IS2[1:0] ei2 sensitivity
These bits define the interrupt sensitivity for ei2
(Port B3) according to Table 6.
Bit 3:2 = IS1[1:0] ei1 sensitivity
These bits define the interrupt sensitivity for ei1
(Port A7) according to Table 6.
Bit 1:0 = IS0[1:0] ei0 sensitivity
These bits define the interrupt sensitivity for ei0
(Port A0) according to Table 6.
Note: These 8 bits can be written only when the I
bit in the CC register is set.

EXTERNAL INTERRUPT SELECTION REGIS-
TER (EISR)
Read/Write
Reset Value: 0000 1100 (0Ch)
Bit 7:6 = ei3[1:0] ei3 pin selection
These bits are written by software. They select the
Port B I/O pin used for the ei3 external interrupt ac-
cording to the table below.
External Interrupt I/O pin selection
* Reset State
Bit 5:4 = ei2[1:0] ei2 pin selection
These bits are written by software. They select the
Port B I/O pin used for the ei2 external interrupt ac-
cording to the table below.
