Removing FRAM71 Memory Modules?

[Dave Frederickson]

When the port is CLAIM'ed in Step 2 memory will be reconfigured. Depending on the size and port number this could be at a low memory address where there could be programs. There's no guarantee that the CLAIM'ed RAM will be empty and the file chain could be corrupted.

As with a physical memory module, devices must be FREEPORT'ed before being removed.

Think of this as a 32k memory module vs a 64k memory module with a battery. When a 32k module is removed it soon looses it's contents and when plugged back in reappears as RAM. The 64k module doesn't loose it's contents and comes back as an IRAM. In the case of FRAM71, maybe only half an IRAM.

My technique reconfigures the device to RAM before being removed from the configuration string so it behaves like the non battery-backed memory module.
