Transferring Memory Contents to Micro Flash RAM
Overview This function works only with Micro controllers. This function copies the memory
contents of a Micro controller to the controller’s flash RAM.
When the Micro controller receives power, it first checks to see if a valid
configuration is present in the data memory. If not, the contents of the flash RAM are
re-loaded into the controller memory.
Flash RAM may be used as an alternative to the optional battery backup, or as an
extra backup of the logic and configuration.
