COP Interface

Is the COP interface documented and where is that information?

The COP interface is an extremely complicated interface and varies in each processor implemen-

tation. Furthermore, it is not currently deﬁned as part of the PowerPC architecture. As a result,

the information concerning this interface is being shared on a limited basis with 3rd party tool

vendors who are using this interface to develop debug tools for the PowerPC microprocessors.

If features like ABIST which are built into the PowerPC processors, and are accessed through the

JTAG/COP port, are required in a speciﬁc design ahve your FAE contact the RISC Applications

group.
