Table 12
Multiplication and Division Instructions (Byte/Word/Long Word) [11 Instructions]
*1: 3 when the result is zero, 7 when an overflow occurs, and 15 normally.
*2: 4 when the result is zero, 8 when an overflow occurs, and 16 normally.
*3: 6 + (a) when the result is zero, 9 + (a) when an overflow occurs, and 19 + (a) normally.
*4: 4 when the result is zero, 7 when an overflow occurs, and 22 normally.
*5: 6 + (a) when the result is zero, 8 + (a) when an overflow occurs, and 26 + (a) normally.
*6: (b) when the result is zero or when an overflow occurs, and 2
× (b) normally.
*7: (c) when the result is zero or when an overflow occurs, and 2
× (c) normally.
*8: 3 when byte (AH) is zero, and 7 when byte (AH) is not zero.
*9: 4 when byte (ear) is zero, and 8 when byte (ear) is not zero.
*10: 5 + (a) when byte (eam) is zero, and 9 + (a) when byte (eam) is not 0.
*11: 3 when word (AH) is zero, and 11 when word (AH) is not zero.
*12: 4 when word (ear) is zero, and 12 when word (ear) is not zero.
*13: 5 + (a) when word (eam) is zero, and 13 + (a) when word (eam) is not zero.
Note : For an explanation of “(a)” to “(d)”, refer to Table 4, “Number of Execution Cycles for Each Type of Addressing,”
and Table 5, “Correction Values for Number of Cycles Used to Calculate Number of Actual Cycles.”
