PPI on BF548 chip

Hello,

  Do I need to use series termination resistors for the PPI data bus when using BF548 chip? I have used for PPI clock and frame sync lines. Is it essential for PPI data bus also? Also, do they need to be of matched lengths? If so, to what accuracies? any controlled impedance traces are required? Are the series resistors used in BF548 EZKIT? I understand that series resistors are required for DDR address, data and control signals as well. But, confused about PPI data bus. Pl clarify.
