26.5.4.2 Data Flash Read

Reading from the Data Flash address space is performed via the AHB bus by addressing the Data Flash address space directly.

Read timings are similar to regular NVM read timings when access size is Byte or half-Word. The AHB data phase is twice as long in case of full-Word-size access.

It is not possible to read the Data Flash area while the NVM main array is being written or erased, whereas the Data Flash area can be written or erased while the main array is being read.
