The operation of saving registers carried out in the interrupt sequence is dependent on whether the SP
at the time of acceptance of an interrupt request, is even or odd. If the stack pointer
register and the PC are saved, 16 bits at a time. If odd, they are saved in two steps, 8 bits at a time.
Figure 9.4.3.2 shows the operation of the saving registers.
