Appendix 6. Machine instructions
Note 15. The number of cycles is the case where the number of bytes to be transferred (i) is even.
When the number of bytes to be transferred (i) is odd, the number is calculated as;
5 ✕ i + 10
Note 16. The number of cycles is the case where the number of bytes to be transferred (i) is even.
When the number of bytes to be transferred (i) is odd, the number is calculated as;
5 ✕ i + 14
Note that it is 10 cycles in the case of 1-byte thanster.
Note 17. i
1
is the number of registers to be stored among A, B, X, Y, DPR0, and PS. i is the number of
2
registers to be stored between DT and PG.
Note 18. Letter “i ” indicates the number of registers to be restored.
1
Note 19. The number of cycles is applied when flag m = “1.” When flag m=“0,” the number is calculated
as;
18 ✕ imm + 5
Note 20. Any value from 0 through 3 is placed in an “n” in op code.”
