MULTIPLE CONNECTIONS TO A SINGLE SERIAL INTERFACE
First Claim
1. An apparatus, comprising:
- a first and a second serial interface, each comprising at least one data line and a power supply line;
a first switching unit coupled to the power supply lines of said first serial interface and said second serial interface, wherein in a first state said first switching unit connects the power supply line of said first serial interface to the power supply line of said second serial interface, and wherein in a second state said first switching unit connects the power supply line of said first serial interface to a first further power supply line, said first further power supply line being configured to be connected to a first power supply; and
a controller configured to control said first switching unit.
