3. Immediate Mode

The first type of memory addressing is immediate mode.

With immediate mode, nothing is fetched from memory. The operand already contains the data to be used.

So the above instruction might simply be saying "Load the contents of the operand (11111111) into the accumulator".

Immediate mode is very useful for instructions involving short constants (as opposed to variables).
