This addressing mode allows that constants be set up at the time
of programming the code. Actual operands can be used, for examples: ADD.L
#7,D0. This instruction adds the number 9 to the contents of data register
D0. The 7 is an immediate operand because the microprocessor does not have
to carry out further memory access to obtain it. The symbol (#) precedes
the operand and indicates to the assembler that the following value is
to be used with the immediate addressing mode. The MC68000 permits byte,
word ,and longword immediate operands.
