The following table shows the TDES2 register bit fields.
Bit
Description
31 - 0
Buffer Address
Indicates the physical memory address of the buffer.
There is no limitation on the transmit buffer address alignment.
The following table shows the TDES3 register bit fields.
Bit
Description
31 - 0
Next Descriptor Address
Indicates the physical memory address of the next descriptor in the descriptor ring.
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.
