This manual provides programming information for the MVME172

Embedded Controller. Extensive programming information is provided for

the Application-Specific Integrated Circuit (ASIC) devices used on the

board. Reference information is included for the Large Scale Integration

(LSI) devices used on the board and sources for additional information are

provided.

This chapter briefly describes the board level hardware features of the

MVME172 Embedded Controller. The chapter begins with a board level

overview and features list. Memory maps are next, and the chapter closes

with some general software considerations such as cache coherency,

interrupts, and bus errors.

All programmable registers in the MVME172 that reside in ASICs are

covered in the chapters on those ASICs. Chapter 2 covers the VMEchip2.

Chapter 3 covers the MC2 chip, and Chapter 4 covers the IP2 chip. Chapter

5 covers the MCECC chip, used only on 200/300-Series MVME172.

Appendix A describes using interrupts. For those interested in

programmable register bit definitions and less interested in hardware

functionality, focus on Chapters 2. 3. 4. and 5. In some cases, however,

Chapter 1 gives related background information.

The MVME172 is based on the MC68060 or MC68LC060

microprocessor. The MVME172 is available in various versions with the

features listed in Table 1-1 on page 1-3. A “No VMEbus” option is also

available.

The I/O connection for the 200/300-Series MVME172 is provided through

four RJ-45 front panel connectors.

The I/O connection for the 400/500-Series serial ports is provided by two

DB-25 front panel I/O connectors. The I/O is connected to the VMEbus P2

connector. The main board is connected through a P2 transition board and

cables to transition boards. The Series 400/500 MVME172 supports the

transition boards MVME712-12. MVME712-13. MVME712M,

MVME712A, MVME712AM, and MVME712B (referred to in this

manual as MVME712x, unless separately specified). These transition

boards provide configuration headers, serial port drivers and industry

standard connectors for the I/O devices. The MVME712 series transition

boards were designed to support the MVME167 boards, but can be used

on the MVME172 by following some special precautions. (Refer to the

section on the Serial Communications Interface in the MVME172

installation and use manual furnished with your 400/500-Series

MVME172. for more information.)

The VMEbus interface is provided by an ASIC called the VMEchip2. The

VMEchip2 includes two tick timers, a watchdog timer, programmable map

decoders for the master and slave interfaces, and a VMEbus to/from local

bus DMA controller, a VMEbus to/from local bus non-DMA programmed

access interface, a VMEbus interrupter, a VMEbus system controller, a

VMEbus interrupt handler, and a VMEbus requester.

Processor-to-VMEbus transfers can be D8. D16. or D32. VMEchip2 DMA

transfers to the VMEbus, however, can be D16. D32. D16/BLT, D32/BLT,

or D64/MBLT.

The MC2 chip ASIC provides four tick timers, the interface to the LAN

chip, SCSI chip, serial port chip, BBRAM, the programmable interface for

the DRAM and/or SRAM mezzanine board, and Flash write enable.

The IndustryPack Interface Controller (IP2 chip) ASIC provides control

and status information, including DMA control, for up to four single size

IndustryPacks (IPs) or up to two double size IPs that can be plugged into

the MVME172 main module.

These boards are designed to conform to the requirements of the following

documents:

VMEbus Specification (IEEE 1014-87)

EIA-232-D Serial Interface Specification, EIA

SCSI Specification, ANSI

IndustryPack Specification, GreenSpring
