5.3 Embedded boot loader mode
The embedded boot loader is located in the System memory and is programmed by ST
during production.
For additional information, refer to AN2606 (Table 2

The USART peripheral operates with the internal 16 MHz oscillator (HSI). The CAN and

(between 4 and 26 MHz) is present.
