6.1.1 EMIF16

  • Check that chip selects go to the proper memory for a correct memory map.
  • Generally, series resistors can be used on the EMIF16 signals to reduce overshoot and undershoot. Acceptable values are 10 Ω, 22 Ω, or 33 Ω.
  • The WAIT signals may have internal pull-down resistors. Be sure they are pulled-up sufficiently, if used.
  • For address lines connection, see the KeyStone architecture external memory interface (EMIF16) user's guide
  • Series termination resistors are recommended on all edge-latching signals like WE and CS.
  • Series resistors are recommended on the bi-directional pins for long routes or when going off-board.
