In one embodiment, an interface may include various mechanisms to handle incoming clock and data signals. More specifically, the interface includes a first multiplexer to receive a first data signal via a serial peripheral interface (SPI) bus coupled to a first pin and a second multiplexer to receive a first clock signal via the SPI bus coupled to a second pin of the first IC and a second clock signal via an inter-integrated circuit (I2C) bus coupled to a third pin. In addition, the interface may include a decoder to receive the second clock signal and a second data signal via the I2C bus coupled to a fourth pin.
