How to use Interrupts for analog pins? Help needed.

The zero-crossing detection circuit provides a 5V pulse every time the AC signal crosses zero volts. We detect this with the Arduino and leverage interrupts to time the trigger circuit precisely in synchronization with these zero-crossing events. The method for …

ESP8266 External interrupts – techtutorialsx

Interrupt priorities determine which interrupt service routine will be called first if two interrupts fire at the same time. Depending on the interrupt controller, some interrupt priorities may be configurable by software. The MSP430 does not support this, all interrupts have a fixed priority. The interrupt priorities on the MSP430 are in descending order from highest address in the vector
