The EMC1212 communicates with a host controller, such as the SMSC KBC1100, through the
proprietary single wire SMSC BudgetBus™ Sensor Interface known as BBUS. The BBUS is a single
wire serial communication protocol between the computer host and its peripheral devices. Please refer
to the BBUS Specification for detailed information about the modes of operation.
