EVM SOFTWARE SETUP AND OPERATION

3.2.2 Detailed Interface

The second interface puts forward all the TPS61310 features through the modeling of internal registers.

Figure 3 illustrates the detailed interface of the evaluation software.

Figure 3. Detailed Interface

The toolbar allows control of parameters which are only accessible through the software. In addition to

normal register Read and Write, the software has an Auto-read and a Write-On-Change function. The I

activity box shows the action (Read or Write), the register address and data, and the number of transfers

between the host and the device. The Watchdog Reset list-box is a DC light dedicated function which is

aimed at refreshing the video mode of the IC.

This interface performs no calculations or computations; it simply reads and writes to and from the IC

registers through the I

C interface.

As explained before, prior to use any features of the device, the ILIM bit must be set. Each register bits

can be changed manually by clicking on the buttons corresponding to each bit in the panel, or can be

changed through the drop-down boxes, check-boxes and buttons. Read-only bits are listed in the

group-box Status/Flags.

The Reset and Read button writes REGISTER0[0]=1 and reads all the registers. Values shown in the

table may differ from those presented in the datasheet as some bits assume two different functions in read

and write operations.
