Table 22
Bit Manipulation Instructions [21 Instructions]
*1: 8 when branching, 7 when not branching
*2: 7 when branching, 6 when not branching
*3: 10 when condition is satisfied, 9 when not satisfied
*4: Undefined count
*5: Until condition is satisfied
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.”
