I'm confused about the use of FRAM read/write. I read the code demo and the programm just define a array like this:
#pragma PERSISTENT(FRAM_write)
unsigned long FRAM_write[WRITE_SIZE] = {0};
The data will be written to FRAM just like this? how do I know it has been written to FRAM rather than RAM or somewhere else?
what if I want to read the data existed after trigging a reset? Can you recommand some more manual or demo to me?
