Can I access internal flash memory using Embedded Coder?

I am working on a project where I use Embedded Coder to deploy to a microcontroller. 

I would like to store data in the microcontroller’s internal flash memory, so that the data is retained even after a power cycle.

I would like to know:

1. Is this feasible?
2. If so, how can I do it?

We do not support any block that directly allows users to write/read to/from the internal flash memory.

To do this, you must use the IO Device Builder app workflow to create your own system object, or the C-Caller block.

Attached is an example model and IOC with you based on the C-Caller implementation. You can use CubeIDE to verify that data is written to the last sector of the flash memory (0x080E0000). Please note that this is just a simple example to demonstrate the use of HAL APIs with C Caller and is not a full-fledged example; you may customize it accordingly.
