Universal asynchronous receiver-transmitter - Wikipedia

An interrupt, in microcontroller context, is a signal that temporarily stops what the CPU is currently working at. Programming using interrupts is very different from the usual top-to-bottom sequence in an Arduino program and thus can be confusing for some.

UART – Realtek IoT/Arduino Solution

/31/2011How do I enable the Rx interrupt on the Arduino? I thought it might be an elegant addition to have the Mega's UART RX interrupt in play, just for the hell of it. Reading the ATMEGA data sheets I know it's possible. And yes, I realise this is overkill, but it …

UART Programming with Atmega128 - Tutorials

There are only two external interrupt pins on the ATmega168 /328 (ie, in the Arduino Uno/Nano/Duemilanove), INT0 and INT1, and they are mapped to Arduino pins 2 and 3. These interrupts can be set to trigger on RISING or FALLING signal edges, or on low level.
