3.2.2 General-purpose registers
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
(AX, BC, DE, and HL).
Registers can be described in terms of function names (X, A, C, B, E, D, L, H, AX, BC, DE, and HL) and absolute
names (R0 to R7 and RP0 to RP3).
