Addressing code

When we say "addressing code," we mean the way CPU interprets the address of the next instruction to be executed, and that depends on the logic of the code itself, which tells the processor whether it should execute instructions sequentially or jump to another location.

Sequential addressing

The default addressing mode for code is sequential addressing, when the instruction pointer (IP) register (IP for 32-bit systems and RIP for 64-bit) contains the address of the instruction following the one being currently executed. There is nothing we need to do in order to put processor into this mode. The instruction pointer is set to the next instruction automatically by the CPU.

For example, when executing...
