Technical Data
Central Processor Unit (CPU)
3.3.1 Accumulator
The accumulator (A) shown in Figure 3-2 is a general-purpose 8-bit
register. The CPU uses the accumulator to hold operands and results of
arithmetic and non-arithmetic operations.
Figure 3-2. Accumulator (A)
3.3.2 Index Register
In the indexed addressing modes, the CPU uses the byte in the index
register (X) shown in Figure 3-3 to determine the conditional address of
Offset, and 9.3.7 Indexed, 16-Bit Offset for more information on
indexed addressing.
The 8-bit index register also can serve as a temporary data storage
location.
