RMFCR is a 16-bit counter that indicates the number of frames missed (discarded, and not
transferred to the receive buffer) during reception. When the receive FIFO overflows, the receive
frames in the FIFO are discarded. The number of frames discarded at this time are counted. When
the value in this register reaches H'FFFF (65,535), the count is halted. When this register is read,
the counter value is cleared to 0. Writes to this register have no effect.
