TMS320F28234: tms320f28234 for external interface with one SARAM CY7C1011CV33

Part Number: TMS320F28234

Hi,

Good Day. I have a customer who is working with TMS320F28234. Please see below his query for your reference.

I am using tms320f28234 for external interface with one SARAM CY7C1011CV33.
The DSP having XINTF peripheral to interface, I am using C2000 driver example "Example_2823xCodeRunFromXintf"
I don't know how to read and write as there is no functions available in the example project.
Can anybody help me by sharing any example code or docs how to read /write using XINTF from CY7C1011CV33 this SARAM.

Best Regards,

Ray Vincent

    Ray,

    The XINTF is designed to act as a transparent bridge between the CPU and external memory. Once a zone is properly configured, CPU reads and writes within the zone's memory range will appear as if the memory is fully integrated into the device. The XINTF will automatically generate the required read and write operations with the external memory to fulfill the CPU requests.

    Ray,

    The XINTF memory regions can be found in the datasheet, where Address 0 of the external memory is mapped to the base address of its Zone:
