MAC DMA Receive Start Command Register (MDRSC Offset 0x000C)
This register is written by the CPU when there are frame data in receive buffer to be processed.
The following table shows the register bit fields.

WO
WRSC Receive Start Command
When written with any value, the Receive DMA checks for descriptors to
be acquired. If no descriptor is available, the receive process returns to
suspended state and waits for the next receive restart command. If
descriptiors are available, the receive process resumes.
This bit is self-clearing.
Transmit Descriptor List Base Address Register (TDLB Offset 0x0010)
This register is used for the Transmit Descriptor List Base Address. The register is used to point to the start of the
appropriate descriptor list. Writing to this register is permitted only when its respective process is in the stopped state.
When stopped, the register must be written before the respective START command is given.
Note: The descriptor lists must be Word (32-bit) aligned. The KSZ8842-PMQL/PMBL behavior is unpredictable when
the lists are not word-aligned.
The following table shows the register bit fields.

Receive Descriptor List Base Address Register (RDLB Offset 0x0014)
This register is used for the Receive descriptor list base address. The register is used to point to the start of the
appropriate descriptor list. Writing to this register is permitted only when its respective process is in the stopped state.
When stopped, the register must be written before the respective START command is given.
Note: The descriptor lists must be Word (32-bit) aligned. The KSZ8842-PMQL/PMBL behavior is unpredictable when
the lists are not word-aligned.

MAC Multicast Table 0 Register (MTR0 Offset 0x0020)
The 64 bit multicast table is used for group address filtering. The hash value is defined as the six most significant bits of
the CRC of the DA. The two most significant bits select the register to be used, while the other determines the bit within
the register.
