CP2200/1
6.6. Sending and Receiving Packets
After reset initialization is complete, the CP2200/1 is ready to send and receive packets. Packets are sent by
loading data into the transmit buffer using the AutoWrite register and writing ‘1’ to TXGO. See “11.2. Transmitting a
Packet” on page 48 for detailed information on how to transmit a packet using the transmit interface. A Packet
Transmitted interrupt will be generated once transmission is complete.
Packet reception occurs automatically when reception is enabled in the MAC and the receive buffer is not full.
Once a packet is received, the host processor is notified by generating a Packet Received interrupt. The host may
read the packet using the AutoRead interface. See “12.2. Reading a Packet Using the Autoread Interface” on
page 58 and “12.4. Initializing the Receive Buffer, Filter and Hash Table” on page 59 for additional information on
using and initializing the receive interface.
