Bit 4 – SM: Sleep Mode
This bit selects between the two available sleep modes. When SM is cleared (zero), Idle
mode is selected as sleep mode. When SM is set (one), Power-down mode is selected
as sleep mode. For details, refer to the paragraph “Sleep Modes”.
Bits3, 2–ISC11, ISC10: Interrupt SenseControl 1 Bit 1 andBit 0
The External Interrupt 1 is activated by the external pin INT1 if the SREG I-flag and the
corresponding interrupt mask in the GIMSK Register is set. The level and edges on the
external INT1 pin that activate the interrupt are defined in Table 5.
Bits 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 is set. The level and edges on the external INT0 pin that
activate the interrupt are defined in Table 6.
The value on the INTn pin is sampled before detecting edges. If edge interrupt is
selected, pulses with a duration longer than one CPU clock period will generate an inter-
rupt. 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. If enabled, a level-triggered interrupt will generate
an interrupt request as long as the pin is held low.
