10.11 BRANCH INSTRUCTION EXECUTION TIMES
Table 10-17, Table 10-18, and Table 10-19 indicate the number of clock cycles required for
execution of the branch, jump, and return 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.
