•
Status Register. A read of this 8-bit register provides information
about the status of the breadboard module. Implemented signals are
"Extended*" and "Passed". There are also provisions for
implementing device-dependent status bits.
•
ID Register. A read of this 16-bit register identifies the
Manufacturer ID number, the Device Class, and the addressing mode
of the Breadboard. This register is implemented as a
Hewlett-Packard A16 register bassed device.
•
Device Type Register. A read of this 8-bit register identifies the
unique card model as defined by the device manufacturer. The card
model number is switch selectable.
•
Control Register. A write to this 8-bit register causes specific
actions to be executed by the device. "Reset" and "System Fail
Inhibit" are implemented. Other device-dependent control bits may
be implemented by the user.
•
Read/Write Operations. Using the backplane interface circuitry
provided, it is possible to read the contents of the Status, ID, or
Device Type Registers onto the data bus (D0- D15), or to write
information into the Control Register from the data bus.
•
DTACK. The interface contains the circuitry required for generating
a delayed DTACK* (data transfer acknowledge) signal.
•
Interrupt Interface. The breadboard module has D16 interrupter
capability. It does not contain an interrupt handler. Interrupt priority
is jumper-selectable for pulling the appropriate interrupt request line
IRQ1* - IRQ7*. Interrupts are generated by the IRQ state machine
on the Interface IC (U6). The daisy-chained IACKIN*/IACKOUT*
signal pair is implemented.
•
Module Reset. Both hardware and software reset signals are
provided to initialize the backplane interface circuitry and your own
custom-designed circuitry to a known state.
•
Backplane Buffering. Buffering is provided for all signals that
interface with the VXIbus backplane.
•
Power Supply. The following power supply voltages (all unfiltered)
are available:
–
+5 VDC, fused at 4 Amps
–
+ 12VAC, fused at 4 Amps
–
-12VAC, unfused
–
+5VDC standby, unfused
