set. Software is then responsible for handling the data in the buffer and then releasing the buffer by writing the ownership
bit back to 0.
If the EMAC is unable to write the data at a rate to match the incoming frame, then an interrupt receive overrun is set. If
there is no receive buffer available, i.e., the next buffer is still owned by software, the interrupt receive buffer not available
is set. If the frame is not successfully received, a statistic register is incremented and the frame is discarded without
informing software.
