T2080 IFC multiplexed Data and ADDR signals

Hi,

This is the first time I am working with the processor.  I have a few doubts about IFC data and address configuration.

I am using 16bit data width NOR Flash with 256MB, the same flash used as a booting device. And for AD pins de-latching, I am using FPGA.

As Processor AD(0:15) pins carry the MSB bits of the address, I will connect those signals to Flash A(0:15) and Processor A(16:26) pins connect to flash A(16:26).

What about the other processor A(27:31) bits, is it has to NC or should be connected/ If it has to be connected where I should connect?

And I need clarity about when we need ADDRESS Shifting and which  ADDR_SHIFT_MODE to be used in our case.

Please respond as soon as possible

Thank You 

Harika

Hi @Har_ika30,

Connect the IFC_A[27:31] pins of processor to its power rails using a resistor if not used.
