INTERRUPTS (Cont’d)
7.6.2 Register Description
EXTERNAL INTERRUPT CONTROL
REGISTER 0 (EICR0)
Read / Write
Reset Value: 0000 0000 (00h)
Bits 7:6 = IS3[1:0] ei3 sensitivity
The interrupt sensitivity, defined using the IS3[1:0]
bits, is applied to the ei3 external interrupts:
These 2 bits can be written only when I1 and I0 of
the CC register are both set to 1 (level 3).
Bits 5:4 = IS2[1:0] ei2 sensitivity
The interrupt sensitivity, defined using the IS2[1:0]
bits, is applied to the ei2 external interrupts:
These 2 bits can be written only when I1 and I0 of
the CC register are both set to 1 (level 3).
Bits 3:2 = IS1[1:0] ei1 sensitivity
The interrupt sensitivity, defined using the IS1[1:0]
bits, is applied to the ei1 external interrupts:

BIts 7:2 = Reserved
Bit 1 = TLIS Top Level Interrupt sensitivity
This bit configures the TLI edge sensitivity. It can
be set and cleared by software only when TLIE bit
is cleared.
0: Falling edge
1: Rising edge
Bit 0 = TLIE Top Level Interrupt enable
This bit allows to enable or disable the TLI capabil-
ity on the dedicated pin. It is set and cleared by
software.
0: TLI disabled
1: TLI enabled
Notes:
– A parasitic interrupt can be generated when
– In some packages, the TLI pin is not available. In
IS01 IS00
clearing the TLIE bit.
this case, the TLIE bit must be kept low to avoid
parasitic TLI interrupts.
