This configuration supports high bandwidth, high efficiency transactions. Often implementations using this mode permit relaxed servicing requirements allowing the PRU to manipulate the received data before transmitting.
Data received in this configuration is passed into the RX L2 buffer. The PRU reads multiple bytes of data from one of the RX L2 banks through the high bandwidth broadside interface and XFR instructions. The PRU can then store or manipulate data before pushing it to the TX L1 FIFO for transmission on the MII TX port.
