Boot configuration

3.2

Embedded boot loader

The embedded boot loader is located in the System memory, programmed by ST during

production. It is used to reprogram the Non Volatile memory using one of the interfaces

listed in Table 3.

For additional information, refer to application note AN2606.

3.3

BOOT0 pin connection

The BOOT0 pin of the Root part number 1 has a lower VIL than the other GPIO (for details

see datasheet I/O static characteristics), thus as it does not fit CMOS requirement, when

driven by another CMOS circuit the signal level must be verified.
