Detailed Description

CAN Message RAM configuration.

The CAN_MsgRamConfig structure contains information used to configure the message RAM. All Rx and Tx buffer elements include a 64 byte payload if CAN FD is enabled. Otherwise, they include an 8 byte payload.

This structure needs to be defined before calling CAN_init() and it must not be changed thereafter.

Note

The Rx FIFO operating mode is not configurable and is always set to blocking to allow for message loss to be detected and reported for proper error handling.
