The PNX17xx Series contains an IDE controller that uses some of the PCI pins and a
few sideband signals. Two external TTL devices are all that is required to interface to
an actual IDE cable/drive. The IDE controller capabilities are:
The PNX17xx Series integrates a 10/100 Ethernet MAC sub-layer of the IEEE 802.3
standard enabling an external PHY to be attached through a Reduced Media
Independent Interface (RMII) or a standard Media Independent Interface (MII). It
implements dual transmit descriptor buffers, support for both real-time and non-real-
time traffic and support for quality of service (QoS) using low-priority and a high-
priority transmit queues. Among other features the 10/100 Ethernet MAC module
includes:
The MAC address is programmable into an MMIO register. The MAC address could
be located in an externally attached EEPROM.
PNX17xx Series fully supports little- and big-endian software stacks.
PNX17xx Series always starts in a fixed endian mode which is determined by the
boot script. There is a system provision for TM5250 software to reset and restart the
TM5250 in the opposite endian mode such that a field software Flash upgrade can
release a ‘endian mode opposite boot’ software upgrade.

all IDE registers are accessible to TM5250 software
Wake-on-LAN power management support. This allows system wake-up using
receive filters or a magic packet detection filter.

Capabilities
not supported on PCI/XIO.
PNX17xx Series PCI/XIO does NOT support external Motorola style masters.
PNX17xx Series assumes that it is always the master over the XIO bus.
