8.2.16 Control Instructions
The control instructions table indicates the number of clock periods needed for the
processor to perform the specified operation. Footnotes specify when it is necessary to
add an entry from another table to calculate the total effective execution time for the given
instruction. The total number of clock cycles is outside the parentheses; the number of
read, prefetch, and write cycles is given inside the parentheses as (r/p/w). These cycles
are included in the total clock cycle number.
