Transmit Descriptor Link List Start Address Register (TXDLSA)
The Tx descriptor defined in EMC is a link-list data structure. The TXDLSA keeps the starting address
of this link-list. In other words, the TXDLSA keeps the starting address of the 1st Tx descriptor. S/W
must configure TXDLSA before enable bit TXON of MCMDR register.

DESCRIPTIONS
The TXDLSA(Transmit Descriptor Link-List Start Address) keeps
the start address of transmit descriptor link-list. If the S/W enables the
bit TXON of MCMDR register, the content of TXDLSA will be loaded
into the current transmit descriptor start address register (CTXDSA).
The TXDLSA doesn’t be updated by EMC. During the operation, EMC
will ignore the bits [1:0] of TXDLSA. This means that each Tx
descriptor always must locate at word boundary memory address.

Receive Descriptor Link List Start Address Register (RXDLSA)
The Rx descriptor defined in EMC is a link-list data structure. The RXDLSA keeps the starting address
of this link-list. In other words, the RXDLSA keeps the starting address of the 1st Rx descriptor. S/W
must configure RXDLSA before enable bit RXON of MCMDR register.
