The following table shows the auto baud performance for a point-to-point connection in X1
mode.
Note:
The CAN Autobaud implemented in the bootloader is efficient only in point-to-point connection.
Because in a point-to-point connection, the transmit CAN message is repeated until a hardware
acknowledge is done by the receiver.
The bootloader can acknowledge an incoming CAN frame only if a configuration is found.
This functionality is not guaranteed on a network with several CAN nodes.
