Boot modes
At startup, boot pins are used to select one out of three boot options:
●
●
●
The boot loader is located in system memory. It is used to reprogram the Flash memory by
using USART1 (PA9/PA10), USART3 (PC10/PC11 or PB10/PB11), CAN2 (PB5/PB15), USB
OTG FS in Device mode (PA11/PA12) through DFU (device firmware upgrade).

Power supply supervisor
The device has an integrated power-on reset (POR) / power-down reset (PDR) circuitry
coupled with a Brownout reset (BOR) circuitry. At power-on, BOR is always active, and
ensures proper operation starting from 1.8 V. After the 1.8 V BOR threshold is reached, the
option byte loading process starts, either to confirm or modify default thresholds, or to
disable BOR permanently. Three BOR thresholds are available through option bytes.
