Register Description
13.2.1 EICRA – External Interrupt Control Register A
The external interrupt control register A contains control bits for interrupt sense control.
Bit 7:4 – Reserved
These bits are unused bits in the Atmel ATmega48PA/88PA/168PA, and will always read as zero.
Bit 3, 2 – ISC11, ISC10: Interrupt Sense Control 1 Bit 1 and Bit 0
The external interrupt 1 is activated by the external pin INT1 if the SREG I-flag and the corresponding interrupt mask are set.
The level and edges on the external INT1 pin that activate the interrupt are defined in Table 13-1. The value on the INT1 pin
is sampled before detecting edges. If edge or toggle interrupt is selected, pulses that last longer than one clock period will
generate an interrupt. Shorter pulses are not guaranteed to generate an interrupt. If low level interrupt is selected, the low
level must be held until the completion of the currently executing instruction to generate an interrupt.
Bit 1, 0 – ISC01, ISC00: Interrupt Sense Control 0 Bit 1 and Bit 0
The external interrupt 0 is activated by the external pin INT0 if the SREG I-flag and the corresponding interrupt mask are set.
The level and edges on the external INT0 pin that activate the interrupt are defined in Table 13-2. The value on the INT0 pin
is sampled before detecting edges. If edge or toggle interrupt is selected, pulses that last longer than one clock period will
generate an interrupt. Shorter pulses are not guaranteed to generate an interrupt. If low level interrupt is selected, the low
level must be held until the completion of the currently executing instruction to generate an interrupt.
