Immediate addressing vs direct addressing
WitrynaAnswer: With register addressing mode, you are moving a byte from one named register to another. It will be a one-byte instruction since there will not be an operand that references an address in RAM or ROM, only a 1-byte op code. Direct addressing involves moving a byte into or out of RAM and wi... Witryna24 sty 2024 · 1. Immediate. With immediate addressing mode, the actual data to be used as the operand is included in the instruction itself. Let's say we want to store operand 1 into a register and then add ...
