Table 10. Burst Configuration Register
(1)
Note: 1. The BCR defines both the read mode and the burst configuration.
2. Synchronous burst length is defined as Word or Double-Word, the data bus width depends only on the WORD input.
Asynchronous Page read is two Words or one Double-Word.
3. A burst length of 8 is not available for x32 organisation.
4. At F
K
> 50MHz when X-Latency = 10 or 12, Y-Latency = 2 independent of the value of M9.
At F
K
= 66MHz when X-Lantency = 14 or 16, Y-Latency = 2 indepedent of the value of M9.
5. Latency 7 valid only for continuous burst. Otherwisw Latency = 8.
6. Latency 10 valid only for continuous burst. Otherwisw Latency = 12.
7. Latency 11 valid only for continuous burst. Otherwisw Latency = 12.
8. Latency 14 valid only for continuous burst. Otherwisw Latency = 16.
