The Arduino Mega series is based on the Atmel AVR ATmega1280 or the ATmega2560. They are almost identical to previous chips but only differs in memory size. These chips have 6 timers. First 3 timers (Timer 0, Timer1 and Timer2) are identical to the ATmega168/328. Timer3, Timer4 and ...
In the end, [rehsd] connected one of the digital pins from the Arduino to an interrupt pin on the computer’s W65C22 versatile interface adapter (VIA). Then eleven more digital pins were connected to the computer, each one representing a state for the mouse and buttons, such as MOUSE_...
Also the minimal bootloader size on mega8. I didn’t really care to make it smaller because of that restriction. It’s been 3 years ago and I moved on to STM32, never been an Arduino fan too… you’re welcome to fork the repo and I’ll happily merge/discuss any changes you have....
that on the Arduino Uno and Mega you don't give it an interrupt number, as perhttp://arduino.cc/en/Reference/attachInterrupt. Rather, your first argument is a pin number of a pin that's supported on that chip (seehttps://github.com/GreyGnome/EnableInterrupt/wiki/Usage#pin--port-...

This is not currently possible with Arduino megaAVR Boards. Arduino megaAVR Boards'attachInterruptwas written to take a pin number as the first parameter, then convert the pin number to interrupt number insideattachInterruptusingdigitalPinToInterrupt, breaking from the convention established in Arduino AV...
This library enables you to use Interrupt from Hardware Timers on an Arduino or Adafruit AVR board, such as Nano, UNO, Mega, AVR_FEATHER32U4, etc.As Hardware Timers are rare, and very precious assets of any board, this library now enables you to use up to 16 ISR-based Timers, while ...
