Figure 1.11.7. Operation of saving registers
The operation of saving registers carried out in the interrupt sequence is dependent on whether the
content of the stack pointer (Note) , at the time of acceptance of an interrupt request, is even or odd. If
the content of the stack pointer (Note) is even, the content of the flag register (FLG) and the content of the
program counter (PC) are saved, 16 bits at a time. If odd, their contents are saved in two steps, 8 bits at
a time. Figure 1.11.7 shows the operation of the saving registers.
Note: When any INT instruction in software numbers 32 to 63 has been executed, this is the stack pointer
indicated by the U flag. Otherwise, it is the interrupt stack pointer (ISP).
(1) Stack pointer (SP) contains even number
[SP] – 5 (Odd)
[SP] – 4 (Even)
[SP] – 2 (Even)
[SP] – 5 (Even)
[SP] – 3 (Even)

(2) Stack pointer (SP) contains odd number
[SP] – 4(Odd)
[SP] – 2(Odd)
[SP]
Note: [SP] denotes the initial value of the stack pointer (SP) when interrupt request is acknowledged.
