VMIVME-7586 Error Notification
Because of a recently discovered design flaw in the VIC64 (Cypress
Semiconductor) used to implement the VMEbus interface on the
VMIVME-7586, VMIC warns users that a malfunction may occur. The
following paragraphs below provide information from Cypress concerning
the conditions that must be present to cause this malfunction.
Cypress Erratum:
The following paragraphs came directly from the 6/13/97 Cypress Erratum (Reference No.95):
Lword and A7-A1 are driven on the VMEbus by a VIC64 slave that is not the addressed slave to the D64
transaction in progress thus corrupting the data of the transaction.The following condition must be met to see
this failure:
1. Defining this misbehaving VIC64 as the “failing slave” and the transaction in which the failure is
noted the “current transaction.”
2. The failing slave was the addressed slave to the transaction immediately preceding the current
transaction.We define this transaction to be the “preceding transaction.”
3. The preceding transaction was a D64 slave read from the failing slave.
4. The current transaction must be a D64 transaction.
5. The preceding transaction exhibits a local “read ahead” cycle which extends (local PAS+ signal is
asserted) beyond the address broadcast phase (first VMEbus DS1/0 deassertion after AS*
assertion) of the current transaction.
Work around, Hardware:
PAS* must be deasserted before DSB (later deassertion of either DS1/0) of the address broadcast cycle of
the current transaction deasserts.
VMIC’s Response:
These conditions may arise if:
1. You have more than one device that may be slave to 64-bit block transfers and at least one has a
VIC64 chip.
2. Block transfer master(s) can reassert AS* and execute a BLT 64 Address Broadcast quickly (less
than about 100 ns AS* hightime).
The VIC64 as used on the VMIVME-7586 does not cause trouble during Master Mode. In other words, the
VMIVME-7586 can safely do master BLT 64 transactions under all conditions.The described malfunction only
occurs when the VIC64 is a BLT 64 slave (read from/by master) and the slave transaction is rapidly followed
by another BLT 64 slave transaction to another slave.

SECTION 1 - INTRODUCTIONTOTHE VMIVME-7586
The VMIVME-7586 single-board microcomputer is a complete IBM PC/AT
80486 compatible microcomputer with the additional beneÞts of Eurocard
construction and full compatibility with the VMEbus SpeciÞcation
Rev. C.1. The VMIVME-7586 also has an industry-standard PC/104
expansion site.
VMICÕs VMIVME-7586 has two operating modes: a standard PC/AT
compatible mode, and a VMEbus controller mode. Upon powerup it
functions as a standard PC/AT. It executes a PC/AT-type power-on
self-test, then boots up MS-DOS, Windows or OS/2 PC/AT compatible
operating system. Its keyboard and video console interaction with the user
is typical of a PC/AT. This PC/AT mode of the VMIVME-7586 is discussed
in Chapter 3 of this manual.
After booting, the VMIVME-7586 may take on the additional functions of a
VMEbus controller and interact with other VMEbus modules. The
VMEbus controller functions are available by programming the
VMIVME-7586Õs VMEbus interface registers according to Chapter 4 of this
manual.
The VMIVME-7586 programmer may quickly and easily control all the
VMIVME-7586 VMEbus functions simply by linking to a library of
VMEbus interrupt and control functions. This library is located in VMICÕs
VMIVME-9420 IOWorks Access software for Windows NT users and
VMIVME-7420
VMEaccess software for MS-DOS users.

1-2 VMIVME-7586 PRODUCT MANUAL
SECTION 2 - ABOUTTHIS MANUAL
Because this product bridges the traditionally divergent worlds of
Intel-based PCs and Motorola-based VMEbus controllers, some confusion
over ÒconventionalÓ notation and terminology may exist. We have made
every effort to make this manual consistent by adhering to conventions
typical for the Motorola/VMEbus world; nevertheless, users in both camps
should review the following notes:
¥ Hexadecimal numbers are listed Motorola-style, preÞxed with a
dollar sign: $F79, for example. By contrast, this same number
would be signiÞed 0F79H according to the Intel convention, or
0xF79 by many programmers. Less common are forms such
as F79
h
or the mathematicianÕs F79
16
.
¥ An 8-bit quantity is termed a Òbyte,Ó a 16-bit quantity is termed a
Òword,Ó and a 32-bit quantity is termed a Òlongword.Ó The Intel
convention is similar, although their 32-bit quantity is more often
called a Òdoubleword.Ó
¥ Motorola programmers should note that Intel processors have an
I/O bus that is completely independent from the memory bus.
Every effort has been made in the manual to clarify this by
referring to registers and logical entities in I/O space by preÞxing
I/O addresses as such. Thus, a register at ÒI/O $140Ó is not the
same as a register at Ò$140,Ó since the latter is on the memory bus
while the former is on the I/O bus.
¥ Intel programmers should note that addresses are listed in this
manual using a linear, Òßat-memoryÓ model rather than the old
segment:offset model associated with Intel Real Mode
programming. Thus, a ROM chip at a segment:offset address of
C000:0 will be listed in this manual as being at address $C0000.
For reference, here are some quick conversion formulas:
Segment:Offset to Linear Address
Linear Address = ( Segment × 16 ) + Offset
Linear Address to Segment:Offset
Segment = (( Linear Address ÷ 65536 ) − remainder ) × 4096
Offset = remainder × 65536
Where remainder = the fractional part of ( Linear Address ÷ 65536 )
Note that there are many possible segment:offset addresses for a single
location.The formula above will provide a unique segment:offset address by
forcing the segment to an even 64 Kbyte boundary, for example, $C000,

$E000, and so forth. When using this formula, make sure to round the offset
calculation properly!

Figure 1-1 shows a simpliÞed view of the VMIVME-7586 board. The
VMIVME-7586 is one member of VMIC's line of PC/AT compatible
VMEbus controllers, all of which combine a standard PC/AT architecture
with the ability to control VMEbus slave boards.
