Hi..
I am using an RM48L952 arm core controller.
It has a 16 bit data bus for external access. I use the 16 bit data bus to access different on board memories like flash, fram, etc.
I have configured the EMIF data bus as a 16 bit bus.When I write a 16 bit data on the bus, i have observed that 3 write enable signals are generated while the chip select is low.
Then, I have configured the EMIF data bus as an 8 bit bus.When I write an 8 bit data on the bus, i have observed that 5 write enable signals are generated while the chip select is low.
I have tried this both in normal mode and select strobe mode, but the result is the same.
Frankly, I am unable to get the relation between chip select signal, write enable and byte enable signals.
Any help is appreciated.
Thanks
