3.3.1 Accumulator
The accumulator (A) shown in Figure 3-1 is a general-purpose 8-bit
register used to hold operands and results of arithmetic calculations or
data manipulations.
3.3.2 Index Register
The index register (X) is an 8-bit register used by the indexed addressing
value to create an effective address. The index register also may be
used as a temporary storage area.
