An immediate value in machine code is a constant or literal value argument. For example, the 6502 assembly instruction:
LDA #$80
...will load the literal value 0x80 (128) into the accumulator (A register).
Note that the value to be loaded comes from an argument within the instruction stream; this contrasts with loading a value from a memory location in a data area, or from another register.
