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.
register direct addressing mode
Direct addressing mode
addressing mode is used to form an instruction format.
Addressing modes of 8051 are 1.Immediate Addressing Mode 2.Register Addressing Mode 3.Register Indirect Addressing Mode 4.Direct Addressing Mode 5.Implied Addressing Mode and 6.Relative Addressing Mode
It is register addressing mode, as it moves the content of HL to PC which is data and not address.

Immediate addressing mode is when one of the operands is "immediately" located after the opcode. It is more correct to say that the operand is part of the instruction.

Stack/explicit.
The CMC (Complement Carry) instruction in assembly language typically uses the implicit addressing mode. In this mode, the instruction operates on the carry flag directly without requiring any operands to be specified. The instruction simply complements the state of the carry flag, changing it from 0 to 1 or from 1 to 0.
