1. Representation:
When using the MCU_MCAN0 of MCU1_0 in TDA4 to receive CANFD data, frame loss rate up to 0.64%.


2. CAN Bus Pressure:
It receives from 22 different CAN IDs, and receives once per 400 microseconds.


3. Current Software - Used Strategy:
3.1 Set up Acceptance Filtering. Divide these 22 different IDs into three groups on average and put them into three receive buffers respectively: Rx Buffers, Rx FIFO0 and Rx FIFO1.
3.2 Whenever new data arrives in these caches, an interrupt will be triggered. In this interrupt handling program, the data will be taken out and put into the queue.
