DESCRIPTION
Reserved
General Purpose Timer Current Count (GPT_CNT). This 16-bit field
reflects the current value of the GP Timer.
DESCRIPTION
Word Swap. If this field is set to 00000000h, or anything except
FFFFFFFFh, the LAN9115 maps words with address bit A[1]=1 to the high
order words of the CSRs and Data FIFOs, and words with address bit
A[1]=0 to the low order words of the CSRs and Data FIFOs. If this field is
set to FFFFFFFFh, the LAN9115 maps words with address bit A[1]=1 to the
low order words of the CSRs and Data FIFOs, and words with address bit
A[1]=0 to the high order words of the CSRs and Data FIFOs.
GPT_CNT-General Purpose Timer Current Count Register
This register reflects the current value of the GP Timer.
WORD_SWAP—Word Swap Control
This register controls how words from the host data bus are mapped to the CRSs and Data FIFOs
inside the LAN9115. The LAN9115 always sends data from the Transmit Data FIFO to the network so
that the low order word is sent first, and always receives data from the network to the Receive Data
FIFO so that the low order word is received first.
