Getting Embedded Flash Descriptor
Figure 19-6. 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
MC_FCR register. The first word of the descriptor can be read by the software application in the
MC_FRR register as soon as the FRDY flag in the MC_FSR register rises. The next reads of the
MC_FRR register provide the following word of the descriptor. If extra read operations to the
MC_FRR register are done after the last word of the descriptor has been returned, then the
MC_FRR register value is 0 until the next valid command
.
