for this example.
Each byte transferred from memory is transmitted across the MII Interface as a byte,
and the MII interface hardware adds the preamble, frame delimiter leader, and the
CRC trailer, if hardware CRC is enabled. Once transmission on the MII Interface
commences, the transmission cannot be interrupted without generating an underrun
error, which is why descriptors and data read commands are issued as soon as
possible and are pipelined. In 10Mb/s and 100Mb/s mode, the output signals look
similar, but in 10Mb/s mode, the transmit clock is scaled down by a factor 10.
In case an RMII PHY is connected, the data communication between the MII
Interface and the PHY is communicated at half the data-width and twice the clock
frequency (50 MHz). In
doubled in the 100Mb/s mode. In 10Mb/s mode, data will only be transmitted once
every 10 clock cycles (an clock gate disables the 50MHz clock for the intervening nine
cycles).
This section outlines the receive process including the activities in the device driver
software.
