Bit Description

7

SDRAM RAS to CAS Delay
0 = 3 clocks
1 = 2 clocks

6

SDRAM CAS Latency
0 = 3 clocks
1 = 2 clocks

5

SDRAM RAS Precharge Time
0 = 3 clocks
1 = 2 clocks

4

EDO DRAM Read Burst timing
0 = Read rate is x333
1 = Read rate is x222

3

EDO DRAM Write Burst timing
0 = Write rate is x333
1 = Write rate is x222

2

EDO RAS Precharge Time
0 = 4 clocks
1 = 3 clocks

1

EDO RAS to CAS Delay
0 = 4 clocks
1 = 3 clocks

0

MA Wait State
0 = Slow (1 wait state for SDRAM, add one clock to all EDO timings)
1 = Fast (0 wait states for SDRAM, clocks run normally for EDO)
