3.3.1 Accumulator
The accumulator (A) shown in Figure 3-2 is a general-purpose 8-bit
register. The accumulator holds operands and results of arithmetic and
non-arithmetic operations.
3.3.2 Index Register
In the indexed addressing modes, the CPU uses the byte in the index
register (X) to determine the effective address of the operand. (See
Indexed, 16-Bit Offset.) The 8-bit index register shown in Figure 3-3
can also serve as a temporary data storage location.
