The RXADRSIZE3 field is used to determine if receive packets are destined for the third of
four mapped address regions. RXADRSIZE3 is compared with the address contained in the
receive packet. If the receive packet address is less than the value in RXADRSIZE3, the
packet address is added to the receive address map offset 3 register (RAMO3) to obtain the
translated address.
