Data registers

There are four data 32-bit data registers: EAX, EBX, ECX, EDX

  • Lower halves of the 32-bit registers can be used as four 16-bit data registers: AX, BX, CX and DX.
  • Lower and higher halves of the above-mentioned four 16-bit registers can be used as eight 8-bit data registers: AH, AL, BH, BL, CH, CL, DH, and DL.
