RWW is supported between Program and Data Flash. Concerning Program Flash this is supported only between the different PFLASH banks. The TC39x has 16Mbytes of internal PFlash and supports 6 banks, 5 (3MByte) and 1 (1MByte). RWW capability is not supported within a single PFLASH bank.
More information can be found in the User's Manual in the Software over the Air (SOTA) chapter.

Please see the NVM chapter for more information on writing/reading to the Flash. As Cwunder says, you can't read and write the same PFlash bank at the same time - writing to a PFlash bank will result in reads from it erroring (unless you are hitting data which has already been cached by the CPU). The writing operation will be handled by the DMU via a command sequence (enter page mode, load page, write page etc), the read will be done via a CPU to the dedicated flash read interface.
