8.3.11 Conditional Branch Instructions
The conditional branch instruction table indicates the number of clock periods
needed for the processor to perform the specified branch on the given branch
size, with complete execution times given. No additional tables are needed to
calculate total effective execution time for these instructions. The total number
of clock cycles is outside the parentheses. The numbers inside parentheses
(r/p/w) are included in the total clock cycle number. All timing data assumes
two-clock reads and writes.
