These bits are unused bits in the Atmel
zero.
When the INT1 bit is set (one) and the I-bit in the Status Register (SREG) is set (one), the
external pin interrupt is enabled. The Interrupt Sense Control1 bits 1/0 (ISC11 and ISC10)
in the External Interrupt Control Register A (EICRA) define whether the external interrupt
is activated on rising and/or falling edge of the INT1 pin or level sensed. Activity on the pin
will cause an interrupt request even if INT1 is configured as an output. The corresponding
interrupt of External Interrupt Request 1 is executed from the INT1 Interrupt Vector.
When the INT0 bit is set (one) and the I-bit in the Status Register (SREG) is set (one), the
external pin interrupt is enabled. The Interrupt Sense Control0 bits 1/0 (ISC01 and ISC00)
in the External Interrupt Control Register A (EICRA) define whether the external interrupt
is activated on rising and/or falling edge of the INT0 pin or level sensed. Activity on the pin
will cause an interrupt request even if INT0 is configured as an output. The corresponding
interrupt of External Interrupt Request 0 is executed from the INT0 Interrupt Vector.
These bits are unused bits in the Atmel ATA6612/ATA6613, and will always read as zero.
When an edge or logic change on the INT1 pin triggers an interrupt request, INTF1
becomes set (one). If the I-bit in SREG and the INT1 bit in EIMSK are set (one), the MCU
will jump to the corresponding Interrupt Vector. The flag is cleared when the interrupt rou-
tine is executed. Alternatively, the flag can be cleared by writing a logical one to it. This
flag is always cleared when INT1 is configured as a level interrupt.
When an edge or logic change on the INT0 pin triggers an interrupt request, INTF0
becomes set (one). If the I-bit in SREG and the INT0 bit in EIMSK are set (one), the MCU
will jump to the corresponding Interrupt Vector. The flag is cleared when the interrupt rou-
tine is executed. Alternatively, the flag can be cleared by writing a logical one to it. This
flag is always cleared when INT0 is configured as a level interrupt.
