121 This driver provides functions to configure and program the Flash memory of all STM32F10x devices,
122 including the latest STM32F10x_XL density devices.
123
124 STM32F10x_XL devices feature up to 1 Mbyte with dual bank architecture for read-while-write (RWW) capability:
125 - bank1: fixed size of 512 Kbytes (256 pages of 2Kbytes each)
126 - bank2: up to 512 Kbytes (up to 256 pages of 2Kbytes each)
127 While other STM32F10x devices features only one bank with memory up to 512 Kbytes.
128
129 In version V3.3.0, some functions were updated and new ones were added to support
130 STM32F10x_XL devices. Thus some functions manages all devices, while other are
131 dedicated for XL devices only.
132
133 The table below presents the list of available functions depending on the used STM32F10x devices.
