Technical Specifications
A.2.1 The PCI Interface
The PCI interface operates as a 32-bit DMA bus master. The connection
is made through edge connector J1, which provides connections on both
the front and back of the board. The signal definitions and pin numbers
conform to the PCI Local Bus Specification Revision 2.2 standard.
Table A.2
and
Table A.3
show the signal assignments.
Note:
The + 3.3 V pins are tied together and decoupled with high
frequency bypass capacitors to ground. No current from
these 3.3 V pins is used on the board. The board derives
power from the + 5 V pins, directly and through a 3.3 V
voltage regulator. The PCI V
I/O
pins are used to
differentiate between a 5 V or a 3.3 V PCI environment.
