8 DIGITAL-LOGIC AG MSM04RS Manual V.5 3 PC/04 BUS SIGNALS AEN, output Address Enable is used to degate the microprocessor and other devices from the I/O channel to allow DMA transfers to take place. low = CPU Cycle, high = DMA Cycle BALE, output Address Latch Enable is provided by the bus controller and is used on the system board to latch valid addresses and memory decodes from the microprocessor. This signal is used so that devices on the bus can latch LA The SA0..9 address lines latched internally according to this signal. BALE is forced high during DMA cycles. /DACK[0..3, 5..7], output DMA Acknowledge 0 to 3 and 5 to 7 are used to acknowledge DMA requests (DRQO through DRQ7). They are active low. This signal indicates that the DMA operation can begin. DRQ[0..3, 5..7], input DMA Requests 0 through 3 and 5 through 7 are asynchronous channel requests used by peripheral devices and the I/O channel microprocessors to gain DMA service (or control of the system). A request is generated by bringing a DRQ line to an active level. A DRQ line must be held high until the corresponding DMA Request Acknowledge (DACK/) line goes active. DRQO through DRQ3 will perform 8-Bit DMA transfers; DRQ5-7 are used for 6 accesses. /IOCHCK, input IOCHCK/ provides the system board with parity (error) information about memory or devices on the I/O channel. low = parity error, high = normal operation IOCHRDY, input I/O Channel Ready is pulled low (not ready) by a memory or I/O device to lengthen I/O or memory cycles. Any slow device using this line should drive it low immediately upon detecting its valid address and a Read or Write command. Machine cycles are extended by an integral number of one clock cycle (67 nanoseconds). This signal should be held in the range of ns. low = wait, high = normal operation /IOCS6, input I/O 6 Bit Chip Select signals the system board that the present data transfer is a 6-Bit, wait-state, I/0 cycle. It is derived from an address decode. /IOCS6 is active low and should be driven with an open collector (300 ohm pull-up) or tri-state driver capable of sinking 20mA. The signal is driven based only on SA5-SAO (not /IOR or /IOW) when AEN is not asserted. In the 8 Bit I/O transfer, the default transfers a 4 wait-state cycle. /IOR, input/output I/O Read instructs an I/O device to drive its data onto the data bus. It may be driven by the system microprocessor or DMA controller, or by a microprocessor or DMA controller resident on the I/O channel. This signal is active low. /IOW, input/output I/O Write instructs an I/O device to read the data on the data bus. It may be driven by any microprocessor or DMA controller in the system. This signal is active low. 8

9 DIGITAL-LOGIC AG MSM04RS Manual V.5 IRQ[ 3-7, 9-2, 4, 5], input These signals are used to tell the microprocessor that an I/O device needs attention. An interrupt request is generated when an IRQ line is raised from low to high. The line must be held high until the microprocessor acknowledges the interrupt request. /Master, input This signal is used with a DRQ line to gain control of the system. A processor or DMA controller on the I/0 channel may issue a DRQ to a DMA channel in cascade mode and receive a /DACK. /MEMCS6, input MEMCS6 Chip Select signals the system board if the present data transfer is a wait-state, 6-Bit, memory cycle. It must be derived from the decode of LA7 through LA23. /MEMCS6 should be driven with an open collector (300 ohm pull-up) or tri-state driver capable of sinking 2OmA. /MEMR input/output These signals instruct the memory devices to drive data onto the data bus. /MEMR is active on all memory read cycles. /MEMR may be driven by any microprocessor or DMA controller in the system. When a microprocessor on the I/0 channel wishes to drive /MEMR, it must have the address lines valid on the bus for one system clock period before driving /MEMR active. These signals are active low. /MEMW, input/output These signals instruct the memory devices to store the data present on the data bus. /MEMW is active in all memory read cycles. /MEMW may be driven by any microprocessor or DMA controller in the system. When a microprocessor on the I/O channel wishes to drive /MEMW, it must have the address lines valid on the bus for one system clock period before driving /MEMW active. Both signals are active low. OSC, output Oscillator (OSC) is a high-speed clock with a 70 nanosecond period (4.388 MHz). This signal is not synchronous with the system clock. It has a 50% duty cycle. OSC starts 00µs after reset is inactive. RESETDRV, output Reset Drive is used to reset or initiate system logic at power-up time or during a low line-voltage outage. This signal is active high. When the signal is active all adapters should turn off or tri-state all drivers connected to the I/O channel. This signal is driven by the permanent Master. /REFRESH, input/output These signals are used to indicate a refresh cycle and can be driven by a microprocessor on the I/0 channel. These signals are active low. SAO-SA9, LA7 - LA23 input/output Address bits 0 through 9 are used to address memory and I/0 devices within the system. These 20 address lines, allow access of up to MBytes of memory. SAO through SA9 are gated on the system bus when BALE is high and are latched on the falling edge of BALE. LA7 to LA23 are not latched and addresses the full 6 MBytes range. These signals are generated by the microprocessors or DMA controllers. They may also be driven by other microprocessor or DMA controllers that reside on the I/0 channel. The SA7-SA23 are always LA7-LA23 address timings for use with the MSCS6 signal. This is advanced AT96 design. The timing is selectable with jumpers LAxx or Saxx. /SBHE, input/output Bus High Enable (system) indicates a transfer of data on the upper byte of the data bus, XD8 through XD5. Sixteen-Bit devices use /SBHE to condition data-bus buffers tied to XD8 through XD5. 9

10 DIGITAL-LOGIC AG MSM04RS Manual V.5 SD[O..5], input/output These signals provide bus bits 0 through 5 for the microprocessor, memory, and I/0 devices. DO is the least-significant Bit and D5 is the most significant Bit. All 8-Bit devices on the I/O channel should use DO through D7 for communications to the microprocessor. The 6-Bit devices will use DO through D5. To support 8-Bit device, the data on D8 through D5 will be gated to DO through D7 during 8-Bit transfers to these devices; 6-Bit microprocessor transfers to 8-Bit devices will be converted to two 8-Bit transfers. /SMEMR input/output These signals instruct the memory devices to drive data onto the data bus for the first MByte. /SMEMR is active on all memory read cycles. /SMEMR may be driven by any microprocessor or DMA controller in the system. When a microprocessor on the I/0 channel wishes to drive /SMEMR, it must have the address lines valid on the bus for one system clock period before driving /SMEMR active. The signal is active low. /SMEMW, input/output These signals instruct the memory devices to store the data present on the data bus for the first MByte. /SMEMW is active in all memory read cycles. /SMEMW may be driven by any microprocessor or DMA controller in the system. When a microprocessor on the I/O channel wishes to drive /SMEMW, it must have the address lines valid on the bus for one system clock period before driving /SMEMW active. Both signals are active low. SYSCLK, output This is a 8 MHz system clock. It is a synchronous microprocessor cycle clock with a cycle time of 67 nanoseconds. The clock has a 66% duty cycle. This signal should only be used for synchronization. TC output Terminal Count provides a pulse when the terminal count for any DMA channel is reached. The TC completes a DMA-Transfer. This signal is expected by the onboard floppy disk controller. Do not use this signal, because it is internally connected to the floppy controller. /OWS, input The Zero Wait State (/OWS) signal tells the microprocessor that it can complete the present bus cycle without inserting any additional wait cycles. In order to run a memory cycle to a 6-Bit device without wait cycles, /OWS is derived from an address decode gated with a Read or Write command. In order to run a memory cycle to an 8-Bit device with a minimum of one-wait states, /OWS should be driven active one system clock after the Read or Write command is active, gated with the address decode for the device. Memory Read and Write commands to an 8-Bit device are active on the falling edge of the system clock. /OWS is active low and should be driven with an open collector or tri-state driver capable of sinking 2OmA. 2V +/- 5% used only for the flatpanel supply and BIAS generation. GROUND = 0V used for the entire system. VCC, +5V +/- 0.25V separate for logic and harddisk/floppy supply. 0

24 DIGITAL-LOGIC AG MSM04RS Manual V.5 7 SPECIAL PERIPHERALS, CONFIGURATION, FUNCTION 7. SCSI-2 Interface (option) The SCSI-2 interface is realized with the Future Domain controller 8C30, which provides a fast synchroneous transfer speed of 0MB/s. The 8C30 is backward compatible with the 8xx family. Internally the 8C30 integrates 2k FIFO and a 6Bit ISA interface. Supported SCSI2-Speed: Asynchroneous: Synchroneous: Fast Synchroneous: 2.5MB/s 5MB/s 0MB/s The boot devices on the SCSI2 interface: - Any SCSI-2 harddisk - Syquest removable media -CDdrives - Tapes and MO-drives During the boot sequence the SCSI-BIOS will treat the removable media as a harddisk, as long as it has the highest SCSI ID and the media is already inserted in the drive. If the media is inserted, then it can not be ejected unless the drive is resetted and the system is turned off. In the case that the media is missing, then the Syquest will be treated as present, with the need for an additional driver. 7.. The operating system support Many operating systems have an embedded CAM like interface, requiring only the selection of a SIM for each SCSI IC to establish communication with SCSI peripherals. The 8C30 SCSI IC is supported by an extensive list of operating systems, as shown in the table below: Operating System: Onboard Support: Driver Support: DOS 5.x / 6.x onboard BIOS none Windows 3. onboard BIOS Power SCSI Novell DOS7 onboard BIOS none MS Windows NT supported by the Win-NT Novell 3. / 4.0 driver available OS/2 V2.x supported by the OS/2 SCO UNIX 3.4 supported by the SCO AT&T/USL UNIX SVR4.2 driver available Solaris V2.0 driver available Unix Ware V.x driver available NeXTSTEP-Intel driver available 24

25 DIGITAL-LOGIC AG MSM04RS Manual V Peripheral support The DOS/Windows environment does not support SCSI peripherals directly. The 8C30 SCSI is supported by many SCSI peripherals via device drivers available from DIGITAL-LOGIC AG. Generally, if your application software is written for either INT3h, ASPI, IBM INT 4Bh or CAM it will work with the 8C30 SCSI IC. Power SCSI, available from Future Domain, supports software that is written for all these interfaces. The table below illustrates the various types of SCSI peripherals and how they are supported under DOS/Windows. SCSI Pheripherals: DOS/Windows: Notes: Fixed Disk 2 IDE + 7 SCSI 7 SCSI drive support CD-ROM 7 drives CD-ROM driver needed Removable Disk drive bootable BIOS support Tape not supported needs a driver Scanner not supported needs a driver 7..3 Software for SCSI Current Future Domain Drivers For installation with a CD-ROM use the disk by Future Domain P/N Multimedia & CD- ROM V4.0 or use the delivered driver from the CD-ROM. If the SCSI Boot-extension in the BIOS from DIGITAL-LOGIC AG doesn t support the environment used by the user then watch out for this driver in the BBS of DIGITAL-LOGIC AG or ask directly FUTURE DOMAIN for it. 25

26 DIGITAL-LOGIC AG MSM04RS Manual V SCSI Cable Interface The user can connect up to 7 SCSI devices. All SCSI devices are daisy chained trough one SCSI-Bus cable. This cable must have terminators at both ends; i.e. the beginning device and end device. An inproper installation of the terminators will cause a SCSI device malfunction. The terminator on the MSboard is active, when jumper J34 is set. The following figures illustrate where the terminators can be placed: Example : Example 2: The boot devices on the SCSI-2 interface: - Any SCSI-2 harddisk - Syquest removable media - CD drives - Tapes, MO- and ZIP-Drives 26

27 DIGITAL-LOGIC AG MSM04RS Manual V.5 8 FAILURES AND HINTS General Information Do not buy a SCSI with fix termination. It only has diodes for the termination (for high voltage). No common connectors (25pin and not 50pin). 8. SCSI driver does not find harddisk Check the cable. Check the terminator at the SCSI. Do not use the SCSI ID SCSI finds too many devices Check the terminator at the SCSI. Do not use the SCSI ID7. 27
