Hi,
We have interfaced a device (TL16C754C) on OMAP-L138 EMIFA.
The timing diagram for the external device for a write operation is given below.
As per above timing diagram it needs t15d (85nS) delay between two read or write operaitons.
But, the EMIFA states that if the current read proceeds with a previous read then there won't be any turn around cycles will be inserted.
I can think of two possibilities to overcome this.
Can you let me know which will be better and if there are any other methods available
- Perform a dummy read and write operation after every write and read operation
- Insert turn around cycles into hold period
I hope my question is clear.
Regards,
GSR
