|-
| B, C, D, E, H, L || 8-bit || General-purpose registers || Can form 16-bit pairs: BC, DE, HL
|-
| A (Accumulator) || 8-bit || Main register for arithmetic, logic, and data transfer || Most used register
|-
| F (Flags) || 8-bit ||
* bit7 - ZF - Zero Flag
* bit6 - NF - Negate Flag (last ALU op was subtract or compare)
