PCI/PCI-X Interfaces and Devices

This board also contains one quad UART (QUART) device connected to the MPC8540
device controller bus to provide additional asynchronous serial ports. The QUART provides
four asynchronous serial ports, SP1 – SP4, which are routed to the P2 connector. Refer to
the ST16C554D Data Sheet listed in
details and/or programming information.
4.10 PCI/PCI-X Interfaces and Devices
The MVME3100 provides three separate PCI/PCI-X bus segments. Bus segment A
operates in 66MHz PCI-X mode and is connected to the MPC8540, the Tsi148 VME
controller, the serial ATA (SATA) controller, and two PCI-X-to-PCI-X bridges. Bus segment
B is bridged between bus A and the two PMC sites and operates in 33/66MHz PCI or
66/100MHz PCI-X mode depending on the slowest speed PMC installed. Bus segment C
is bridged between bus A, the USB controller, and the PMCspan connector. Bus C operates
at 33MHz PCI mode.
4.10.1

MPC8540 PCI-X Interface

The MPC8540 PCI-X controller is configured to operate in PCI-X mode only, host bridge
mode. Bus A mode switch must be in OFF position in order to be fixed in PCI-X mode. The
mode cannot be changed by software. Refer to the MPC8540 Reference Manual listed in
Appendix B, Related
information.
4.10.2

TSi148 VME Controller

The VMEbus interface for the MVME3100 is provided by the TSi148 ASIC. The TSi148
provides the required VME, VME extensions, and 2eSST functions. Transceivers are used
to buffer the VME signals between the TSi148 and the VME backplane. Refer to the TSi148
User's Manual listed in
programming information.
4.10.3

Serial ATA Host Controller

The SATA host controller uses the Silicon Image SiI3124A PCI-X to Serial ATA Controller.
This device provides four SATA channels at 1.5Gb/s and is compliant with the Serial ATA:
High speed serialized AT Attachment Specification, Revision 1.0. It also supports the native
command queuing feature of SATA II.
