Hi Sadaf,

Please refer the XINTF example in controlSUITE for the same.

Sadaf,

You can refer either example to understand how to setup the XINTF module. Once XINTF is setup, use the zone address to read/write access.

Hi,
This is my very first controller. i have never worked on embedded systems before.
I have configured the xintf from the example but im unable to find registers on which i should put data for in/out. how to access an address at which i want to send data. Is there a function in which i could give the address and data. For example Write(Address, data) and when this function is executed the data will be written at the specified address.

Can you please give me a code for a simple write to external interface.

Sadaf,

Just do -
*(int * (zone_address)) = write_data;
