27.6.4.2 RWWEE Read

Reading from the RWWEE address space is performed via the AHB bus by addressing the RWWEE address space directly. Refer to the figures in 27.6.2 Memory Organization for details.

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 RWWEE area while the NVM main array is being written or erased, whereas the RWWEE area can be written or erased while the main array is being read.

The RWWEE address space is not cached, therefore it is recommended to limit access to this area for performance and power consumption considerations.
