MC68340 USER’S MANUAL

MOTOROLA

5.7.3.7 BINARY-CODED DECIMAL AND EXTENDED INSTRUCTIONS. The BCD and

extended instruction table indicates the number of clock periods needed for the processor

to perform the specified operation using the specified addressing mode. 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.
