11. Transmit Interface
11.1. Overview
The CP2200/1 provides a simple interface for transmitting Ethernet packets requiring the host to only load the
source and destination addresses, length/type, and data into the transmit buffer. All other IEEE 802.3
requirements, such as the preamble, start frame delimiter, CRC, and padding (full-duplex only), are automatically
generated. Figure 16 shows a typical Ethernet packet.
