Receive Missed-Frame Counter Register (RMFCR)

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 is counted. When

the value in this register reaches H

′FFFF, counting-up is halted. When this register is read, the

counter value is cleared to 0. Write operations to this register have no effect.
