18.4.1
The EtherC transmitter assembles the transmit data on the frame and outputs to MII when there is
a transmit request from the E-DMAC. The data transmitted via the MII is transmitted to the lines
by PHY-LSI. Figure 18.3 shows the status change of the Ether-C transmitter. This operation is the
same between ports 0 and 1. The priority of the process when transmit frame from E-DMAC and
relay frame transmission collide can be set by the Transmit/Relay Priority Control Mode register
(TSU_PRISL0/1).
