For each incoming frame, the CRC is calculated by the MII_G_RT and compared against the CRC included in the frame. When the two values do not match, a CRC error is flagged. The ERROR_CRC indication is available in the register interface (PRU R31 Receive Interface) as well as in the FIFO interface (RX L2 Status Interface). It is also provided to the INTC which is integrated in the PRU_ICSSG. Figure 6-243 shows the inputs and outputs of CRC error detection logic block.
