A general-purpose register consists of eight 8-bit registers (X, A, C, B, E, D, L, and H).
In addition each register being used as an 8-bit register, two 8-bit registers in pairs can be used as a 16-bit register
Registers can be described in terms of function names (X, A, C, B, E, D, L, H, AX, BC, DE, and HL) and absolute
