Is there a possibility to write a whole word to the IO Pins? I would like to connect a 8bit parallel Interface to the Arduino.
Is there a possibility to write a whole word to the IO Pins?
Like "Sit"? Or "Fetch"?
word is a bastard from Redmond, and has not place on the Arduino.
Look at "Direct Port Manipulation". If you have an Arduino that has 8 pins on one port that are all available, you can write 8 bits (not a word) at once. But, the 328-based machines don't have a full port available.
Thank you PaulS. That was what I'm looking for. I want to use the Mega with enough free ports.

Then just use Direct Port Manipulation - PORTx writes a byte to the port and PINx reads a byte
