What are patterns of bits sent to or read from GPIO pins called? I want to call them “words”, but I’m uncertain if this is how they are referred to in documentation for the use of a header board that might plug into an ardino board.
So if you have a sequence of ONs and OFFs being read or sent from a microcontroller board are those called words?  What are they called?
Here is a simplistic diagram.
Larger than 8 bits is usually referred to as WORD.
