1.2.5.7 Memory Driver Configuration

Since the Demo Meter application needs to read/write data information from/to an external memory, the Memory Driver is used to access an available external memory in the Development Boards through QSPI.

Figure 1-58. External Memory Access Through QSPI

The Datalog application defines and manages different regions depending on the data information to be stored in the external memory:

Metrology region
User calibration region
TOU (Time of Use) region
RTC region
Console region
Events region
Energy region
Demand region

The following image shows the configuration of the Memory Driver module:

The Memory Driver is configured in Asynchronous mode to avoid blocking program execution during write operations.
