Host
Figure 5. Identifier Remapping
The communication with a device (CAN node) must be opened prior to initiate any ISP
communication.
To open communication with the device, the Host sends a “connecting” CAN message
(ID_SELECT_NODE) with the node number (NNB) passed in parameter.
If the node number passed is equal to FFh then the CAN bootloader accepts the communication
(Figure 6).
Otherwise the node number passed in parameter must be equal to the local Node Number (Fig-
ure 7).
