In the 8086 microprocessor, register indirect addressing mode is a method of accessing data in memory using a register to hold the address of the data. In this mode, the effective address of the operand is provided by a register, such as BX, SI, or DI. This allows for flexible data manipulation, as the contents of the register can be easily modified to point to different memory locations. This addressing mode is particularly useful for operations on arrays and data structures.

What is addressing mode of instruction?
Addersing mode of a microprocesso tells the programmer that in which mode the instruction works . There are 5 addressing mode in 8080 , viz. Direct , register, indirect , immidiate ,implict addressing modes.
What is the difference between register addressing mode and register indirect addressing mode?
Ans: In the register addressing mode the operands are in registers which reside within the CPU. Register-mode instructions are 1-byte instructions and can be executed within the CPU without the need to reference memory for operands. But in the Register-indirect addressing mode the instruction specifies a register or a pair of registers in the processor whose contains give the address of the operand in memory. This mode uses 1-byte instructions even though the operand is in memory. Before using a register-indirect mode instruction, the programmer must ensure that the address of the operand is placed in the processor register with a previous transfer-type instruction. A reference to the register is then equivalent to specifying a memory address.
In which addressing mode the effective address of the operand is generated by adding a constant value to the content of a register?
its register indirect with displacement.

register direct addressing mode
What is register indirect?
Register indirect addressing is a mode of addressing in computer architecture where the address of the operand is held in a register rather than being specified directly in the instruction. When an instruction uses register indirect addressing, the CPU accesses the memory location pointed to by the register to retrieve or store data. This approach allows for more flexible and efficient memory access, as the address can be easily modified by changing the value in the register. It is commonly used in assembly language and low-level programming for tasks like pointer manipulation.
