A.2 Operational Environment
A.2.1
The PCI Interface
A-4
The LSIU40HVD is designed for use in PCI computer systems with an
ISA/EISA bracket type. The LSI Logic SDMS software operates the
board, but the design of the board does not prevent the use of other
software.
The PCI interface operates as a 32-bit DMA bus master. The connection
is made through the 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 2.1
standard. The following tables 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 PCI portion of
the LSI53C876 chip is powered from the 3 V/5 V pins.
