Description

On how to configure RAT, please go through Configuring OptiFlash various IP.

This application configures RAT to translate a region with starting address 0x70200000 and size of 32KB that would translate to 0x70000000 and both of these addresses are in OCRAM. So when writing to address 0x70200000 would actually write to 0x70000000. At 0x70000000 address buffer array has been placed using memory configurator. Therefore, All that is written at address 0x70200000, can be read from buffer variable. This function is being displayed through this example.
