1.2 General Description
CPCPCI is a PCI plugin card for the CAN bus. Designed for
industrial series applications CPCPCI has a robust and cost efficient
layout. CPCPCI supports up to four CAN controller of type NXP
SJA1000.
CPCPCI maps the CAN controller into the PC address space and
thus allows access to CAN messages with low latency. Existing
software for the supported CAN controller can easily be adapted.
With CPCPCI the CAN communication may be handled either in
interrupt controlled or in polled mode.
CPCPCI can optionally be delivered with galvanic decoupling of the
CAN bus. The dual and four channel version has the additional
option of galvanic decoupling between the CAN channels.
For applications with restricted space available, like embedded PCs,
there is also a "low profile" version available.

2 Programming Interface
CPCPCI is mapped into the PC memory space with a base address
assigned by the PC BIOS. The availability of the CAN controller(s) in
the memory area makes the CAN communication direct and provides
a low latency time. The card is identified by the following parameters:
Vendor ID : 0x10B5
Device ID : 0x9030
Subvendor ID : 0x10B5
Subsystem ID : 0x4000
CPCPCI incorporates a PLX9030 PCI to local bus bridge. BAR0 of
the PCI configuration space register points to the bridge registers,
whereas BAR2 plus an offset of 0x400 points to the first SJA1000
CAN controller. At offset 0x600, 0x800 and 0xA00 of BAR2 the
optional second, third and fourth SJA1000 CAN controller can be
accessed.
Please contact EMS Dr. Thomas Wünsche for more detailed
information about the programming interface of CPCPCI.
