Web28 apr. 2024 · 1 Answer. You can't, at least address the register's name directly in an instruction. That's because 8051 instructions were designed to be encoded with a single byte, or a byte plus an immediate. That byte contains the opcode and 3 bits for the register number. Thus you can only encode 8 registers in the instruction. incandescent artinyaWeboperand. This register, which holds the address, is called the pointer register and is said to point to the operand.
