Yes, there are 20 different interrupt sources on NanoCore12! These are all user-enabled, so that an interrupt can be made to occur on such events as: * an input pin logic-level changes * the hardware timer overflows * the hardware free-running counter matches a user-defined value * a byte has been received via the serial port There are also two interrupt input pins. XIRQ (PE0) and IRQ (PE1) on the 32-pin and 40-pin versions, which can be used to signal NanoCore12 when some external event has occurred. Additionally, any of the interrupts can be used to trigger a wake-up of NanoCore12 from sleep mode. These are very important advantages that NanoCore12 has over similarly-priced stamp-sized modules.
