RXDLSA
DESCRIPTIONS
The RXDLSA(Receive Descriptor Link-List Start Address) keeps
the start address of receive descriptor link-list. If the S/W enables the
bit RXON of MCMDR register, the content of RXDLSA will be loaded
into the current receive descriptor start address register (CRXDSA).
The RXDLSA doesn’t be updated by EMC. During the operation, EMC
will ignore the bits [1:0] of RXDLSA. This means that each Rx
descriptor always must locate at word boundary memory address.
MAC Command Register (MCMDR)
The MCMDR provides the control information for EMC. Some command settings affect both frame
transmission and reception, such as bit FDUP, the full/half duplex mode selection, or bit OPMOD, the
100/10M bps mode selection. Some command settings control frame transmission and reception
separately, likes bit TXON and RXON.
