Pin Change Interrupt Timing
Register Description
ATmega325P/3250P
EICRA – External Interrupt Control Register A
An example of timing of a pin change interrupt is shown in
Figure 12-1. Pin Change Interrupt
The External Interrupt Control Register A contains control bits for interrupt sense control.
• 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 corre-
sponding interrupt mask are set. The level and edges on the external INT0 pin that activate the
interrupt are defined in
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.
