Generate: In this mode, a device is sending data to the Local bus.

Consume: In this mode, a device is receiving data from the Local bus.

Pipeline: In this mode, a device is neither generating nor consuming data. Data is passed through from the device on the left to the device on the right.

Append: In this mode, a device pipelines the data until the end-of-frame flag is detected. When the flag is detected, the device appends its block of data and sets new end-of-block and end-of-frame flags.

Insert: In this mode, the device places a block of data and an end-of-block flag on the Local bus, and then pipelines data from the device on the left to the device on the right.

Strip: In this mode, a device alternates between the pipeline and consume modes. It removes a block of data from the beginning of each frame.

Eavesdrop: In this mode, a device is simultaneously consuming and pipelining data. It copies each byte of data as it is passed along.

Transform: In this mode, a device generates and consumes data.
