I am not able to read the register content of the NAT 9914

[rushcom]

I am interfacing the ARM7 uC & the NAT 9914 ,for D 0-7 is provided via 3.3-5V converter.

The CE,WE Dbin & the RS0-2 is provided directly to the NAT 9914.

I am following the sequence

For setting the

1.RS0-2

Then pulling the CE.

then Pulling the WE (in write cycle)

Then placing the data in D0-7 as provided in the timing dia in the NAT 9914's datasheet.

I have reffered to the reference manual,Datasheet & AN110.

I am follwing all the steps for initialization i have attached my hardware schematic & the program (in Embedded C).

You can run the program in keiluVision 3.

Tell me if any more pins need the buffer in the hardware.

Tell me if i am missing any steps.

When I am trying to read the RDISR0

I am strucked at this point so tell me if i am doing any mistake

I am attaching the Hardwarre schematic & the Program in txt format.

When i am executing the program i am having low on D0-7 the pin of the NAT9914
