58 / 147 page  High-Performance Small Form Factor Single-Chip Ethernet Controller with HP Auto-MDIX Support Datasheet Revision 2.9 (03-01-12) 58 SMSC LAN9211 DATASHEET 3.12.6.3 TX Example 3 In this example a single, 111-Byte Ethernet packet will be transmitted with a TX checksum. This packet is divided into four buffers. The four buffers are as follows: Buffer 0: 4-Byte “Data Start Offset” 4-Byte Checksum Preamble 16-Byte “Buffer End Alignment” Buffer 1: 7-Byte “Data Start Offset” 79-Bytes of payload data 16-Byte “Buffer End Alignment” Buffer 2: 0-Byte “Data Start Offset” 15-Bytes of payload data 16-Byte “Buffer End Alignment” Buffer 3: 10-Byte “Data Start Offset” 17-Bytes of payload data 16-Byte “Buffer End Alignment” Figure 3.21, "TX Example 1" illustrates the TX command structure for this example, and also shows how data is passed to the TX data FIFO. Note: In order to perform a TX checksum calculation on the associated packet, bit 14 (CK) of the TX Command ‘B’ must be set in conjunction with bit 13 (FS) of TX Command ‘A’ and bit 16 (TXCOE_EN) of the COE_CR register. For more information, refer to Section 3.6.2, "Transmit Checksum Offload Engine (TXCOE)". |
