10.9 SHIFT/ROTATE EXECUTION TIMES
Table 10-13 indicates the number of clock cycles required for execution of the shift and
rotate instructions. The number of operand read and write cycles is shown in parentheses
(r/w). Where indicated, the number of clock cycles and r/w cycles must be added to those
required for effective address calculation.
10.10 BIT MANIPULATION AND BIT FIELD EXECUTION TIMES
Table 10-14 and Table 10-15 indicate the number of clock cycles required for execution of
the bit manipulation instructions. The execution times for the bit field instructions is shown
in Table 10-16. The number of operand read and write cycles is shown in parentheses (r/w).
Where indicated, the number of clock cycles and r/w cycles must be added to those required
for effective address calculation.
