External Interrupts
A typical and general setup for interrupt vector addresses in ATtiny48/88 is shown in the pro-
gram example below.
Note:
The External Interrupts are triggered by the INT0 and INT1 pins or any of the PCINT[27:0] pins.
Observe that, if enabled, the interrupts will trigger even if the INT0 and INT1 or PCINT[27:0] pins
are configured as outputs. This feature provides a way of generating a software interrupt, as
follows.
The PCMSK3, PCMSK2, PCMSK1 and PCMSK0 registers control which pins contribute to the
pin change interrupts. Pin change interrupts on PCINT[27:0] are detected asynchronously. This
Assembly Code Example
• Pin Change Interrupt PCI3 triggers if a pin in PCINT[27:24] is toggled while enabled
• Pin Change Interrupt PCI2 triggers if a pin in PCINT[23:16] is toggled while enabled
• Pin Change Interrupt PCI1 triggers if a pin in PCINT[15:8] is toggled while enabled
• Pin Change Interrupt PCI0 triggers if a pin in PCINT[7:0] is toggled while enabled
