STM32F10x_XL devices feature up to 1 Mbyte with dual bank architecture for read-while-write (RWW) capability:
- bank1: fixed size of 512 Kbytes (256 pages of 2Kbytes each)
- bank2: up to 512 Kbytes (up to 256 pages of 2Kbytes each)
While other STM32F10x devices features only one bank with memory up to 512 Kbytes.
In version V3.3.0, some functions were updated and new ones were added to support
STM32F10x_XL devices. Thus some functions manages all devices, while other are
dedicated for XL devices only.
