configuration and control registers
The HPC3130 register set is accessible through either a generic parallel bus interface or a two-wire serial
interface. Eight bytes of register space are provided per slot. Since the HPC3130 supports four slots, a total of
32 bytes of registers is implemented. Register and bit descriptions are provided in the following sections and
indicate the bits that are common to all slots. The bit default values are given, which represent the state of the
HPC3130 after a PCI reset event. After a PCI reset, the HPC3130 drives outputs to a state such that the slots
appear as if they were not a hot-plug platform.
The register map that follows provides the register overview. Byte addressing is required when accessing the
internal registers. Read transactions from reserved registers return zeros.
