Instruction Execution Timing
10.8 SINGLE-OPERAND INSTRUCTION EXECUTION TIMES
Table 10-11 shows the number of clock cycles required for execution of the single-operand
instructions. The number of operand reads 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.
Execution times for the CLR instruction are given in Table 10-12. The number of operand
reads and writes is shown in parentheses (r/w).
