[STM32H743XGH6] Flash memory

I believe the STM32H743XGH6 has 1 MB of internal flash memory. However, using STM32CubeProgrammer, I was able to write and read data to the reserved area at 0x8180 0000. Is it okay to use this area?

The built-in Flash Memory areas of the STM32H743XGH6 are recognized as
0x8100 0000-0x817F FFFF and 0x8000 0000-0x0801 FFFF.
