Addressing mode

Answer 1

The INX rp instruction uses the Register Pair Addressing Mode. In this instruction, the register pair (BC, DE, or HL) is specified directly within the instruction itself, and the operation is performed internally in the CPU registers. It does not access memory and simply increments the 16-bit content of the specified register pair by 1.
