Register Description
ATtiny4/5/9/10
EICRA – External Interrupt Control Register A
Figure 9-1.
The External Interrupt Control Register A contains control bits for interrupt sense control.
• Bits 7:2 – Res: Reserved Bits
These bits are reserved and will always read zero.
• 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 corre-
sponding interrupt mask are set. The level and edges on the external INT0 pin that activate the
interrupt are defined in
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
