CAN Autobaud
CAN Autobaud
Limitation
4251B–CAN–03/08
The table below shows the autobaud 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 in-coming CAN frame only if a configuration is found.
This functionality is not guaranteed on a network with several CAN nodes.
‘–’ indicates an impossible configuration.
