BudgetBus Protocol
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.
The BudgetBus timing is shown in Figure 2.1. This timing applies to all BudgetBus communication bits.
