Memory Organization
There are four separate memory areas in the motion controller, each with
a different function. These four memory areas are shown in the following
diagram.
Firmware
The Firmware, stored in EPROMs, is downloaded to working memory
(dynamic RAM) whenever you apply power to the controller, or press the
RESET button. This allows the firmware to execute much faster than if
the EPROMs were accessed directly.
Note: You can only change firmware by replacing the EPROMs or, in
the 1394 GMC Turbo, by performing a Flash EPROM update
procedure.
