MC68340 USER’S MANUAL

MOTOROLA

5.7.3.11 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.
