Interface control

摘要

An apparatus, method and computer program, the apparatus comprising: communication circuitry configured to drive, on a first occasion, a first transition of a first electrical parameter on an electrical interface to another apparatus; determination circuitry configured to determine feedback information dependent upon a measured electrical parameter on the electrical interface; and control circuitry configured to use the determined feedback information to control the power output of the communication circuitry to achieve, on a second occasion subsequent to the first occasion, the first transition of the first electrical parameter on the electrical interface within a threshold time period.

1. An apparatus, comprising:
communication circuitry configured to communicate information to a further apparatus by driving, on a first occasion, a first transition of an electrical parameter on a wired electrical data communications interface; determination circuitry configured to determine feedback information from the first transition of the electrical parameter on the wired electrical data communications interface by measuring the electrical parameter on the wired electrical data communications interface; and control circuitry configured to use the determined feedback information to control the power output of the communication circuitry, when a time period of the first transition of the electrical parameter on a wired electrical data communications interface is not within a threshold time period, to achieve, on at least a second occasion, a time period of a second transition of the electrical parameter on the wired electrical data communications interface within the threshold time period, wherein the second occasion is the next time after the first occasion that the communication circuitry drives a transition of the electrical parameter on the wired electrical data communications interface.
