Bit Descriptions:
When a transmit pause command is processed, the MAC Control Type is inserted in the
transmit frame as the ethernet type field.
The format of a transmit pause frame is:

1. Destination address = Individual address[6] (6 bytes)
2. Source address = Individual address[0] (6 bytes)
3. Type field = MAC Control Type (2bytes)
4. Opcode = 0x0001 (2bytes)
• The destination address must match one of first two individual addresses, with the
• The Ethernet type field must match MAC Control Type.
• The first two data bytes of the frame must equal 0x0001.

MAC Control Type. The MAC Control Type field defines
the Ethernet type field for receive and transmit MAC
control frames. This is used in the processing of transmit
and receive pause frames, which are a special form of
MAC control frames. For a receive frame to be identified
as a pause frame, the following conditions must be met:
Transmit Pause Time. When a transmit pause command is
processed, the Transmit Pause Time is inserted as the
actual time to pause.
