The title is quite self descriptive. I ask this question because I found contradicting information in the atmel web page. I need two external interrupts to control one rotary encoder. One interrupt control pulses from one pin (both rising and falling) and the other iterrupt the same for the other pin. So if I has only 1 it doesn't work for me.
Visiting the product page at atmel I read that it has 6 Ext. Interrupts: http://www.atmel.com/devices/attiny85.aspx
The datasheet I only see int0 references (page 47) , and I don't quite understand the datasheet http://www.atmel.com/Images/Atmel-2586-AVR-8-bit-Microcontroller-ATtiny25-ATtiny45-ATtiny85_Datasheet.pdf
