Table 9. Configuration Register Definitions (Continued)
CR13–CR10 = Initial Burst Access Delay Configuration (IAD3-IAD0)
Speed Options 54D, 64C, 65A:
0000 = 2 CLK cycle initial burst access delay

0010 = 4 CLK cycle initial burst access delay
0011 = 5 CLK cycle initial burst access delay
0100 = 6 CLK cycle initial burst access delay
0101 = 7 CLK cycle initial burst access delay
0110 = 8 CLK cycle initial burst access delay
0111 = 9 CLK cycle initial burst access delay—Default
CR9 = Data Output Configuration (DOC)
0 = Hold Data for 1-CLK cycle—Default
1 = Reserved
CR8 = IND/WAIT# Configuration (WC)
0 = IND/WAIT# Asserted During Delay—Default
1 = IND/WAIT# Asserted One Data Cycle Before Delay
CR7 = Burst Sequence (BS)
0 = Reserved
1 = Linear Burst Order—Default
CR6 = Clock Configuration (CC)
0 = Reserved
1 = Burst Starts and Data Output on Rising Clock Edge—Default
CR5–CR3 = Reserved For Future Enhancements (R)
These bits are reserved for future use. Set these bits to “0.”
CR2–CR0 = Burst Length (BL2–BL0)
000 = Reserved, burst accesses disabled (asynchronous reads only)
