Methods of changing a data rate of communication over an interface between a data transmitter and a data receiver are disclosed, wherein the data transmitter is associated with a first processor and transmitting data over the interface and the data receiver is associated with a second processor. The data transmitter transmits and the data receiver receives data over the interface at a first data rate. At the first processor, it is determined to change the first data rate to a second data rate. The data transmitter transmits and the data receiver receives a request to change the first data rate to the second data rate. In response thereto, a response message is transmitted by the data receiver and received by the data transmitter. When the response message comprises an acknowledgement to change the first data rate to the second data rate, the data transmitter transmits and the data receiver receives data over the interface at the second data rate. Corresponding protocol, electronic circuit and electronic device are also enclosed.
