The register save operation performed in an interrupt sequence differs depending on whether the con-
tent of the stack pointer (SP)
If the stack pointer (SP)
counter (PC) each are saved simultaneously all 16 bits together. If the stack pointer indicates an odd
number, the register contents each are saved in two operations 8 bits at a time. Figure 5.3.3 shows how
registers are saved in each case.

Address
[SP] denotes the initial value of the stack pointer (SP) when interrupt request is acknowledged.
After the microcomputer finishes saving registers, the SP content is [SP] minus 4.
