1. The gray color is used for reserved Flash memory addresses.
The information block is divided into two parts:
•
System memory is used to boot the device in System memory boot mode. The area is
reserved for use by STMicroelectronics and contains the boot loader which is used to
reprogram the Flash memory through one of the following interfaces: USART1,
USART2 or USB (DFU). It is programmed by ST when the device is manufactured, and
protected against spurious write/erase operations. For further details, please refer to
the AN2606 available from www.st.com.
