Does MPC5777C have a dedicate NVM block that can be accessed without using C55FMC flash controller?

I want to set a few "flags or strings" before the reset event and read it back in the next boot up.

We had initially thought of using flash memory that is by using the C55FMC controller. Is there an alternate way for storing smaller data that will retain after reset? because we could not find it in the reference manual.

As discussed in:

So we do not have an alternate option other than using SRAM instead of C55FMC?

@lukaszadrapa  can you please confirm?

There's only flash and RAM, I can't see other option.
