Preliminary data sheet
2.1 Chip I/O and System Interconnections
Figure 1
On the left-hand side, the LAN100 is connected to the off-chip Ethernet PHY using
the Media Independent Interface (MII) or Reduced Media Independent Interface
(RMII), which includes transmit, receive, and management connections. On the
right-hand side, the LAN100 is connected to the on-chip system buses:

The MMIO control port of the LAN100 allows CPU access to the LAN100’s
internal registers via the internal DCS bus of the PNX17xx Series. The LAN100
MMIO port is a slave on the DCS bus.
The Direct Memory Access (DMA) port of the LAN100 performs DMA via the
internal MTL bus of the PNX17xx Series. The LAN100 can initiate transactions
while it is a master on the MTL bus. The LAN100 has multiple DMA interfaces to
allow both non-real-time and real-time transmit modes, and receive mode.
