But in this case, it is inverse, so at first the source address will be given. Source, Destination. In this Immediate Addressing Mode, the data is provided in the instruction itself. The data is provided immediately after the opcode. So here the data is provided directly after the opcode. In this mode, the operands are not in the memory. So for an example, we can say that CLC. This instruction is used to clear the carry flag, and set it to 0.
So it does not take any operand. So here also the operand is not in the memory.
In the direct addressing mode, the operands are located in memory. In this case the address space is 00H to FFH so it is also called the page 0 addressing mode. The direct addressing mode takes two Bytes of memory space. So it takes less time to execute. So for fast accessing the data from these locations, RAM generally starts from H.
