ST10F276Z5 new standard bootstrap loader program flow
Other than after a normal reset the watchdog timer is disabled, so the bootstrap loading
sequence is not time limited. Depending on the selected serial link (UART0 or CAN1), pin
TxD0 or CAN1_TxD is configured as output, so the ST10F276Z5 can return the
acknowledge byte. Even if the internal IFLASH is enabled, a code cannot be executed from
it.
