T89C51CC01 CAN Bootloader
The CAN is used to transmit information has the following configuration:
•
•
•
Two ways are possible to initialize the CAN controller:
•
•
The selection between these two solutions is made with EB:
•
•
CANBT1:3 and EB can be modified by user through a set of API or with ISP commands.
The figure below describes the CAN controller flow.

Standard Frame CAN format 2.0A (identifier 11-bit)
Frame: Data Frame
Baud rate: autobaud is performed by the bootloader
Use the software autobaud
Use the user configuration stored in the CANBT1, CANBT2 and CANBT3
EB = FFh: the autobaud is performed.
EB not equal to FFh: the CANBT1:2:3 are used.
