The RX error detection logic tracks the receive error signaled by the physical layer and informs the PRU-ICSS INTC whenever an error is detected. Figure 30-55 shows the inputs and outputs of the RX error detection logic block. Note the following dependencies:
Figure 30-55 RX Error DetectionThis submodule also keeps track of a running count of receive error events within a 10 μs error detection window, as shown in Figure 30-56. The INTC is notified when 32 or more events have occurred in a 10 μs error detection window. The error detection window is not a sliding window but a non-overlapping window with no specific initialization time with respect to incoming traffic. The timer starts its 10 μs counts immediately after de-assertion of reset to the MII_RT module.
