The USART peripherals operate at the internal 16 MHz oscillator (HSI) frequency.
The embedded bootloader code is located in system memory. It is programmed by ST
during production. For additional information, refer to application note AN2606.
Physical remap in STM32F410
Once the boot pins are selected, the application software can modify the memory
accessible in the code area (in this way the code can be executed through the ICode bus in
place of the System bus). This modification is performed by programming the Section 7.2.1:
SYSCFG memory remap register (SYSCFG_MEMRMP) in the SYSCFG controller.
The following memories can thus be remapped:
• Main Flash memory
• System memory
• Embedded SRAM
