Getting Embedded Flash Descriptor
Figure 20-6. Command State Chart
This command allows the system to learn about the Flash organization. The system can take full
advantage of this information. For instance, a device could be replaced by one with more Flash
capacity, and so the software is able to adapt itself to the new configuration.
To get the embedded Flash descriptor, the application writes the GETD command in the
EEFC_FCR register. The first word of the descriptor can be read by the software application in
the EEFC_FRR register as soon as the FRDY flag in the EEFC_FSR register rises. The next
reads of the EEFC_FRR register provide the following word of the descriptor. If extra read oper-
