When using the LPC54616 chip, if you want to receive BRS during CANFD, you only need to configure CANFD and BRS bit during initialization, right? The following figure is attached (Message ram and interrupt have been configured successfully, standard frames and FD frames without brs can be accepted normally)
Hi,
As the following Fig, when you use FD(Flexible Data rate), the classical data size is 8 Bytes, but using FD feature can extend the data size in one CAN frame.
You have to configure the FDF, BRS, DLC bits for both the transmitter and receiver frames. Because the control/ID bits and data bits transfer in different rate, so you have to define two CAN bit rate.
Pls refer to section 35.14.1.3 CAN FD operation in UM10912.pdf.
Hope it can help you
