1. Tx buffer 3 (identifier = 1: it is the highest priority between all other dedicated Tx buffers and it has a higher priority than the oldest pending Tx FIFO: Tx buffer 7)
2. Tx buffer 0 (identifier = 3: it is the highest priority between all other dedicated Tx buffers and it has higher priority than the oldest pending Tx FIFO: Tx buffer 7)
3. Tx buffer 7 (because it is the oldest pending Tx FIFO with identifier =4 and has higher priority between all dedicated Tx buffers)
4. Tx buffer 8 (because it is the oldest pending Tx FIFO with identifier =2 and has the highest priority between all dedicated Tx buffers)
5. Tx buffer 4 (identifier = 8: it has the highest priority between all other dedicated Tx buffers and the Tx FIFO is empty)
6. Tx buffer 2 (identifier = 12: it has the highest priority between all other dedicated Tx buffers and the Tx FIFO is empty)
7. Tx buffer 1 (identifier = 15: it has the highest priority between all other dedicated Tx buffers and the Tx FIFO is empty)
8. Tx buffer 5 (because it is the only pending dedicated Tx buffer)
在此示例中,元素按以下顺序发送(假设所有专用Tx缓冲区请求已启用):
1. Tx buffer 3 (identifier = 1: it is the highest priority between all other dedicated Tx buffers and it has a higher priority than the oldest pending Tx FIFO: Tx buffer 7)
2. Tx buffer 0 (identifier = 3: it is the highest priority between all other dedicated Tx buffers and it has higher priority than the oldest pending Tx FIFO: Tx buffer 7)
