WRP swapped banks, Ref Manual clarification

The reference manual (RM0440 Rev 7) has a point about WRP on page 125 regarding if the two banks are swapped. Why do the WRP2A_STRT and WRP2A_END registers have two different sets of values? It looks like one set is for Single Bank mode and the other set is what you would find in Dual bank mode, but the order doesn't match the above and there are no notes to describe why the same register has two different numbers for the same protection area. It is really unclear what is meant by this.

Hello D_wight,

Correct should be only 2 first lines:

– WRP2A_STRT = 0x62.

– WRP2A_END = 0x70.

Next 2 lines should be removed. This is mistake in RM0440 - it will be corrected in next RM0440 release.

Regards and Thanks for report
