NOTE:
The save procedure writes application data to Flash-EPROM. The
save procedure does not affect application data in RAM.
RESULT: If there is sufficient space in the Flash EPROM, the controller begins
saving application data in RAM to Flash EPROM and displays the
message: burning Flash EPROM, please wait.
When done, the display window lists system data.
If the message “Couldn’t burn EPROM” displays, check that the
controller has a Flash EPROM. If it does and there are no hardware
problems, the Flash EPROM is probably out of memory. Erase the
Flash EPROM (previous procedure) and try to save again.
