Figure 3-2. Stacking Order
3.3 Accumulator (A)
The accumulator is a general-purpose 8-bit register used to hold
operands and results of arithmetic calculations or data manipulations.
3.4 Index Register (X)
The index register is an 8-bit register used for the indexed addressing
value to create an effective address. The index register may also be
used as a temporary storage area.
3.5 Condition Code Register (CCR)
The CCR is a 5-bit register in which the H, N, Z, and C bits are used to
indicate the results of the instruction just executed, and the I bit is used
to enable or disable interrupts. These bits can be individually tested by

NOTE:
Since the stack pointer decrements during pushes, the PCL is stacked first,
followed by PCH, etc. Pulling from the stack is in the reverse order.
