The values of
Access, or during Data Write Access, when the number of wait-states on the external data space is 0
(MEMCONFR:DWS = 0, see section 2.7.3.1). For Data Write Access Timing, When DWS > 0 (DWS = number
of data wait-states), the time which is taken by the wait-states, should be added to the appropriate TV (TV =
Table Value = the appropriate value from the table, above).
