Serial communication over communication control pin

A method comprising:

• detecting, by a device including a data interface having a first communication control pin and a second communication control pin, a current flow at the first communication control pin, the current flow caused by at least a pull-up resistor and a source of power;
• and
• communicating, by the device when the current flow is detected at the first communications pin, serial data via the second communication control pin at the data interface.

A non-transitory computer-readable storage medium including computer program code which when executed by at least one processor circuitry causes operations comprising:

• detecting, by a first device including a data interface, a current flow at a first communication control pin at the data interface;
• and
• assigning, by the first device based on the detection of the current flow at the first communication control pin, serial data communication circuitry to a second communication control pin at the data interface to carry serial data communications to another device.
