Note: Operation is shown for the 32-bit data bus. Figure shown with 3-CLK initial access delay configuration, linear address,
4-doubleword burst, output on rising CLD edge, data hold for 1-CLK, IND/WAIT# asserted on the last transfer before wrap-
around.

8.4.2
Initial Burst Access Delay
Initial Burst Access Delay is defined as the number of clock cycles that must elapse from the first
valid clock edge after ADV# assertion (or the rising edge of ADV#) until the first valid CLK edge
when the data is valid. Burst access is initiated and the address is latched on the first rising CLK
edge when ADV# is active or upon a rising ADV# edge, whichever comes first. The Initial Burst
Access Delay is determined in the Configuration Register (CR13-CR10). Refer to Table 8.5 for the
initial access delay configurations under CR13-CR10. See Figure 8.4 for the Initial Burst Delay
Control timing diagram. Note that the Initial Access Delay for a burst access has no effect on
asynchronous read operations.
