85 / 130 page  High-Performance Single-Chip 10/100 Ethernet Controller with HP Auto-MDIX Datasheet SMSC LAN9218 85 Revision 1.5 (07-18-06) DATASHEET 5.3.16 GPT_CNT-General Purpose Timer Current Count Register This register reflects the current value of the GP Timer. 5.3.17 WORD SWAP—Word Swap Control This register controls how words from the host data bus are mapped to the CSRs and Data FIFOs inside the LAN9218. The LAN9218 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. Offset: 90h Size: 32 bits BITS DESCRIPTION TYPE DEFAULT 31-16 Reserved RO - 15-0 General Purpose Timer Current Count (GPT_CNT). This 16-bit field reflects the current value of the GP Timer. RO FFFFh Offset: 98h Size: 32 bits BITS DESCRIPTION TYPE DEFAULT 31:0 Word Swap. This field only has significance if the device is operated in 16- bit mode. In 32-bit mode, D[31:15] is always mapped to the high order word and D[15:0] is always mapped to the low order word. In 16-bit mode, if this field is set to 00000000h, or anything except 0xFFFFFFFFh, the LAN9218 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 0xFFFFFFFFh, the LAN9218 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. Note: Please refer to Section 3.6.1, "32-bit vs. 16-bit Host Bus Width Operation" for additional information. R/W NASR 00000000h |
