7-2 Pico GFX Control Commands

The master transmits a control command to initiate data exchange

between the communication partners. The slave always returns an

answer to this request, which indicates whether data has been

exchanged or not. An error code will be returned if data exchange has

failed. This code is precisely defined in the ODVA specifications.
