8.2.18 Save and Restore Operations
The save and restore operations table indicates the number of clock periods needed for
the processor to perform the specified state save or return from exception, with complete
execution times and stack length given. No additional tables are needed to calculate total
effective execution time for these operations. 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.
