Hi Tristan, I've put your code online, revision 2252 contains the new file. There is only one change: I renamed the wd! into !wdc. It tells "store to watchdog control" and follows the more or less informal convention that ! and @ can be preceeded with size information and followed by location

[Amforth] AVR8 watchdog (reset and interrupt) atmega328p

AVR8 watchdog (reset and interrupt) atmega328p I wanted to use the 128 kHz watchdog oscillator as an additional timer. I saw that AVR8 watchdog timer and reset was addressed on the mailing list in late 2013 using assembler.frt In the source tree there is an assembler word -wdt (no-wdt.asm),
