Read data from RX SRAM. After the read of this command, the read pointer of
internal SRAM is unchanged. And the DM9008A starts to pre-fetch the SRAM data
to internal data buffers.
Read data from RX SRAM. After the read of this command, the read pointer of
internal SRAM is unchanged
Read data from RX SRAM. After the read of this command, the read pointer is
increased by 1or 2 depends on the operator mode (8-bit or16-bit respectively)
Write data to TX SRAM. After the write of this command, the write pointer is
unchanged
Write Data to TX SRAM
After the write of this command, the write pointer is increased by 1 or 2, depends on
the operator mode. (8-bit or 16-bit respectively)
