Missed Packet Count Register (MPCNT)
The MPCNT keeps the number of packets that were dropped due to various types of receive errors.
The MPCNT is a read clear register. In addition, S/W also can write an initial value to MPCNT and the
missed packet counter will start counting from that initial value. If the missed packet counter is
overflow, the MMP of MISTA will be set.

MAC Receive Pause Count Register (MRPC)
The EMC of W90P710 supports the PAUSE control frame reception and recognition. If EMC received
a PAUSE control frame, the operand field of the PAUSE control frame will be extracted and stored in
the MRPC register. The MRPC register will keep the same while Tx of EMC is pausing due to the
PAUSE control frame is received. The MRPC is read only and write to this register has no effect.
