System bus signals are controlled dynamically according to the specific
memory controller machine that handles the current bus transaction.
All functions starting with H belong to the host port. Its data bus width is
selected at power-on reset by the value of DSI64. Multiplexing between
host port functions is selected by the DSI control registers. For details on
DSI interface refer to Chapter 14, Direct Slave Interface (DSI).

The least significant 32 data lines on this shared bus are configured during
the power-on reset configuration sequence to serve as the least significant
system bus data lines, the Ethernet MII/RMII lines (only the used lines are
connected), or the least significant DSI data lines. The signal line
assignment is determined at power-on reset by the value of the DSI64
reset configuration pin and, if DSI64 = 0, by the ETHSEL bit in the hard
reset configuration word (HRCW). If DSI64 = 0 during power-on reset and
HRCW[ETHSEL]= 0 (the default), the signal lines are assigned to system
bus data and designated as Dn. If DSI64 = 0 and HRCW[ETHSEL] = 1, the
signal lines are assigned to the Ethernet interface (MII or RMII) and are
designated as ETHxxx. If DSI64 = 1, the pins are assigned to DSI data bus
and are designated as HDn.
Multiplexing between Ethernet functions is selected by the Ethernet block
control registers according to the mode (disabled, MII, or RMII). Unused
pins in any mode should be left unconnected. For details on the Ethernet
interface, refer to Chapter 25, Ethernet Controller.
Multiplexing between host port functions is selected by the DSI control
registers. See Chapter 14, Direct Slave Interface (DSI). All functions
starting with ETH belong to the Ethernet block.
