The maximum baud rate (B
still does not exceed the limit, that is, all baud rates between B
deviation limit. The maximum standard baud rate that fulfills this requirement is 19200 baud.
Higher baud rates, however, may be used as long as the actual deviation does not exceed
the limit. A certain baud rate (marked “I” in
limit, while an even higher baud rate (marked “II” in
depends on the host interface.
Standard bootstrap with CAN
Features
The bootstrap via CAN has the same overall behavior as the bootstrap via UART:

BSL initialization time, > 1ms @ fCPU = 40 MHz.
Zero frame (CAN message: standard ID = 0, DLC = 0), sent by host.
CAN message (standard ID = E6h, DLC = 3, Data0 = D5h, Data1-Data2 = IDCHIP_low-high), sent by the ST10F276Z5 on
request.
128 bytes of code / data, sent by host.
Caution: CAN1_TxD is only driven a certain time after reception of the zero byte (1.3ms @ fCPU = 40 MHz).
Internal Boot ROM / Test-Flash.
Same bootstrapping steps;
Same bootstrap method: Analyze the timing of a predefined frame, send back an
acknowledge frame BUT only on request, load a fixed number of bytes and run;
Same functionalities: Boot with different crystals and PLL ratios.
