The buffer address must be Word aligned.
PCI Configuration Registers
The KSZ8841-PMQL implements 12 configuration registers. These registers are described in the following subsections.
The KSZ8841-PMQL enables a full software-driven initialization and configuration. This allows the software to identify
and query the KSZ8841-PMQL. The KSZ8841-PMQL treats configuration space write operations to registers that are
reserved as no-ops. That is, the access completes normally on the bus and the data is discarded. Read accesses, to
reserved or unimplemented registers, complete normally and a data value of 0 is returned.
Software reset has no effect on the configuration registers. Hardware reset sets the configuration registers to their
default values.
