    Two programmable Local-to-PCI interrupts. • Endian Byte Swapping. Note that not all of these features are pertinent to the PMCDIO64 - see section "A.1 PCI9030 PCI Interface (on page 17)" for further details of the device. Copyright  2000 BVM Ltd.

  • Page 11: Main Logic

    PMCDIO64 Main Logic The PMCDIO64 uses a Xilinx SpartanXL FPGA connected to the 16-bit local bus to provide the on- board logic functions as described below. 3.3.1 Input Register A 64-bit Input Register containing a latched version of the I/O pins on the logic device. The signal is latched by the 33MHz PCI clock.

  • Page 12: I/O Interface

    - see section "5.2.2 LK9 to LK12 P5 Common Select (on page 9)" for further details. 93CS56 EEPROM The PMCDIO64 is fitted with a 93CS56 EEPROM which is supplied pre-programmed by BVM. The contents of this EEPROM are read by the PCI9030 on coming out of reset and are used to set up the control registers after reset, configuring the PCI interface configuration, PCI Device/Vendor ID's &...

  • Page 13: Installation

    (two on the front panel and two on the spacers). 4. There is no voltage keying on the PMCDIO64, it will work in both +3.3V and +5V host carriers. 5. The PMCDIO64 can be used with a BVM supplied connecting lead to standard 9-pin D-type connectors, or a user supplied alternative.

  • Page 14: Configuration

    5.2.1 LK1 to LK8 I/O Pull-Up Enable The digital I/O signals to the PMCDIO64 may be pulled-up to +5V via 10KΩ resistor networks in groups of 8 if link selected. See the table below for link to I/O equivalence. LINK...
