AURIX TC3XX SOTA

Dear All,

I want to invalidate the previous UCB_SWAP_ORIG and UCB_SWAP_COPY entries. I could not understand  below statement. "The previous (x-1) UCB_SWAP entry is invalidated by over-programming all-1 into CONFIRMATIONL(x-1)  and CONFIRMATIONH(x-1)". 

Can someone clarify if I have to overwrite CONFIRMATIONL(x-1)  = 0x11111111 and CONFIRMATIONH(x-1) = 0x11111111 or else?

Also, what means "over-programming" here? In general we usually erase the sector and then write bytes into memory.

Thanks in advance.
