Other PowerSpan Initializations

It is necessary to initialize the PowerSpan Interrupt Map registers in a specific way, in order to use the interrupt pins as specified for the 4538. This can be done by the local processor during its boot and/or by the PCI host.

The following C code is an example of interrupt pin initialization.
