Option bytes in STM32F207

[HXiao.1]

Hi 

It stated in PM0059 page 16:  The value of an option is automatically modified by first erasing the user configuration sector and then programming all the option bytes with the values contained in the FLASH_OPTCR register.

I want to  know : What's the user configuration sector? Can you help to point to the right ones in the following table?

The option bytes and the user configuration sector are one and the same.

I guess technically the option bytes are within the user configuration sector. But that's the only thing in there. They refer to the same location in flash.
