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
the operand. See
9.3.5 Indexed, No Offset
,
9.3.6 Indexed, 8-Bit
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.
