Flash reading, if MCU is read protected

Hi.

When read protection level 1 is applied to MCU, is it possible to read flash content somehow?

I would like to store CPU status register, PC and some other variables into flash in case of hard fault. But MCU was read protected with level 1 before. If I get such (defected) part back, is it possible to read those statuses and variables from flash? I would have one dedicated flash page only for that.

Or is it maybe possible to leave only that page unprotected?

Thanks
