3. VMEbus interface
3.1. Address interface
The i4000 can be selected to accept either short addressing, using 16 bit addresses
(A16) or standard addressing, using 24 bit addresses (A24).
When using short addressing up to 32 i4000 boards can be put in a single VMEbus
system since the lower 11 address lines (A0-A10) are used internally on the i4000. If
standard addressing is used, a larger address space is available to select the board.
The memory space occupied by the i4000 is $800 bytes long. This memory space is
equally spread across the four modules. so each module occupies $200 bytes. From
these $200 bytes address space half is used by the interrupt controller. The address
space for each module is therefore $100 bytes long (8 bit addressing).
The address space of the i4000 is selectable using dip switches (SW1 and SW2) which
are accessible even when the four module slots are occupied. When a switch is "on" the
corresponding address line is a logical "zero" and when a switch is "off" the
corresponding address line is "one".
Address modifier AM4 can be used to select either standard or short memory
addressing. If AM4 is "one" (the switch is in the off position) standard addressing is
selected. If AM4 is "zero" (switch on) short addressing is selected. When using short
addressing the address lines A16-A23 are don't cares.

3.2. The interrupter
The i4000 has a special interrupter which is largely compatible with the M68C153. The
interrupter is a so called D08(O) type interrupter which means that the interrupter
during an interrupt acknowledge cycle will put a status byte on the data line D0-D7. The
interrupter has one interrupt level (IRQ1-IRQ7) selectable by dip switches (SW3) for all
the modules. Each module can generate its own vector.
There are two classes of interrupters which are both supported by the i4000: release on
acknowledge (ROAK) or release on register access (RORA). The ROAK interrupter
negates its interrupt request line in response to an interrupt acknowledge cycle. This
mechanism will work with all handlers. The RORA interrupter releases its request when
the handler accesses an on-board register during the interrupt service routine. The
handler performs the acknowledge cycle but the interrupter does not immediately
negate its request. Sometime during the service routine the handler will have to write to
a register on the interrupter which causes it to negate the request.

4. Module installation
4.1. Mounting the module
A maximum of four modules can be fitted on the i4000 base board. To plug in a module
slide the module from above under an angle on top of the i4000 and first position the
25-pole sub-D connector through the openings in the front cover. Then position the
24-pole female header on top of the corresponding header on the base board. Push the
module until the 40-pole header connector is positioned and press the module with care
in its place.
The module can be secured in its position using two or four screws (M3 * 5mm). The
older modules only have mounting provisions for the two screws on the 25-pole sub-D
connector but the newer modules have two additional screws to secure the module.
4.2. P2 connector assignments
Peripherals can be connected to M-modules in two ways. On the front side of the
module a 25-pole sub-D connector (or mechanically equivalent) can be used to connect
cables on the front panel of the VMEbus base board. Alternatively, a 24-pole header
connector interfaces the I/O signals to the base board where they are connected to the
VMEbus P2 connector.
In 32 bit VMEbus systems the backplane for the P2 connector must either be removed
for the i4000 slot or an i4000 without the P2 connector must be ordered. In that case
the peripherals can be connected to the M-module up front.
Figure 5 Orientation of 24-pole header connector
Every M-module has 24 pins of the P2 connector assigned. Four modules on a base
board can then use this I/O path.
This division into four pads of the P2 connector enables so called "module connector" to
be plugged into the back of a 96-way shroud, mounted on the "P2-backplane". On the
96-way connector 3 pins are not used for every module. Several manufacturers produce
these "module connectors, which can be coded and sometimes have latches.

5. Software issues
5.1. Address mapping
As mentioned before the address space occupied by the i4000 board is $800 bytes
(A0-A10). These $800 bytes are divided into 4 identical spaces. Every $200 bytes block
is assigned to a module slot. The first $100 byte address space is assigned to the
module itself and the second $100 byte is used for the access part of the interrupt
controller.
Using this method of address decoding provides an identical address map for each
module on the i4000 board. This makes writing the software easier since just the base
address of the module, not the base address of the i4000 has to be known. Every
module has its own Interrupt-Vector and Interrupt-Control register. The $100 bytes from
each module used to access the interrupt controller are not completely decoded. Both
registers of the Interrupt controller are mirrored several times within the $100 bytes
address space. If the module itself the $100 bytes completely decodes, depends on the
used module.
Address Map of the i4000:
$000..$0ff Module
$101 Control register (CR0) Module 0
$103 Vector register (VR0)
$200..$2ff Module
$301 Control register (CR1) Module 1
$303 Vector register (VR1)
$400..$4ff Module
$501 Control register (CR2) Module 2
$503 Vector register (VR2)
$600..$6ff Module
$701 Control register (CR3) Module 3
$703 Vector register (VR3)
The base address of a module can be calculated using the following formula:
ModuleBaseAddress = i4000BaseAddress + ModuleNumber * $200
EXAMPLE:
The installed base address of the i4000 is $800000. A module is fitted into slot 2. The
module base address is then $800000 + 2 * $200 = $800200. When using a 32 bit
master which accesses the standard address space at address $ffxxxxxx, then the

P.O. Box 627, 5340 AP OSS, The Netherlands Fax: [phone]
module will be accessed at address $ff800200. The corresponding interrupt control
register address is then $ff800301.
5.2. The interrupt controller
5.2.1. Functional description
The Interrupt controller used with the i4000 is largely compatible the MC68153
Interrupt controller from Motorola.
The interrupt controller provides a means for the modules to ask for an interrupt of the
processor activity and receive service from the processor. The Interrupt controller on the
i4000 acts as an interface device requesting and responding to interrupt acknowledge
cycles for up to 4 independent modules.
5.2.2. Register description
The Interrupt controller of the i4000 contains 8 programmable registers. There are four
control registers (CR0-CR3) that govern operation of the Interrupt controller and four
vector registers (VR0-VR3) that contain the vector data used during an interrupt
acknowledge cycle. Every module is assigned one register pair.

Write only
L2-L0 (Interrupt level, dummy bits)
The least significant 3-bit field of the register determines the level at which an
interrupt will be generated.
These three bits are NOT used in the i4000 interrupt controller since the interrupt
level for all the four modules is selected via dip switches. However to maintain
software compatibility with the A201 it is advisable to program these 3 bits with
the same interrupt level as the dip switches.
IRAC (Interrupt Auto-Clear)
If the IRAC is set (Bit 3), IRE (Bit 4) is cleared during an interrupt acknowledge
cycle responding to this request. This action of clearing IRE disables the module
interrupt request. To re-enable the module interrupt request associated with this
register, IRE must be set again by writing to the control register.
IRE (Interrupt enable)
This field (Bit 4) must be set (high level) to enable the module interrupt request
associated with the control register. Thus, if the module asserts IRQ and IRE is
cleared, no interrupt request to the VMEbus will be generated.
X/IN* (External/Internal)
Bit 5 of the control register determines the response of the i4000 interrupt
controller during an interrupt acknowledge cycle. If the X/IN* bit is clear (low
level) the Interrupt Controller will respond with vector data and a DTACK* signal,
i.e., an internal response. If X/IN* is set, the vector is not supplied and no DTACK*
is given by the Interrupt Controller, i.e., an external module should respond.
RESERVED
These two bits are not used in the current implementation of the Interrupt
Controller and reserved for future use.

P.O. Box 627, 5340 AP OSS, The Netherlands Fax: [phone]
5.2.4. Vector registers
Each module interrupt input has its own associated vector register. Each register is 8 bits
wide and supplies a data byte during its interrupt acknowledge cycle if the associated
External/Internal (X/IN*) control register bit is clear (zero). This data can be status,
identification, or address information depending on system usage. The information is
programmed by the system user.
5.2.5. Interrupt controller reset
When a VMEbus reset is applied, the control registers of the i4000 interrupt controller
are set to all zeros (low). The vector registers however are uninitialized and should be
programmed before use.
