INTERRUPTS (Cont’d)
7.6 EXTERNAL INTERRUPTS
The pending interrupts are cleared writing a differ-
ent value in the ISx[1:0], IPA or IPB bits of the
EICR.
Note: External interrupts are masked when an I/O
(configured as input interrupt) of the same inter-
rupt vector is forced to V
7.6.1 I/O PORT INTERRUPT SENSITIVITY
The external interrupt sensitivity is controlled by
the IPA, IPB and ISxx bits of the EICR register
(Figure
independent external interrupt source sensitivities.
24). This control allows to have up to 4 fully
SS
.
Each external interrupt source can be generated
on four (or five) different events on the pin:

To guarantee correct functionality, the sensitivity
bits in the EICR register can be modified only
when the I1 and I0 bits of the CC register are both
set to 1 (level 3).
