6.2. SMBus Interface Demonstration
The TC-RTC Evaluation Board can be loaded with firmware that can enable an SMBus/I
described in the following sections.
6.2.1. Firmware Download
The TC-RTC Evaluation Board comes preloaded with firmware that enables the UART interface. In order to enable
the SMBus interface, alternate firmware has to be loaded on the device. The steps in this section will guide you
through downloading the TC-RTC firmware with SMBus interface to the TC-RTC evaluation board.
1. Install the Silicon Laboratories IDE from the Reference Design Kit CD. Launch the IDE by choosing "Start
2. Depending on which type of debug adapter you have, set up the hardware as shown in one of the two diagrams
