TUSS44x0 EVM for Ultrasonic Sensors User's Guide
To modify the values of the grid, the user can enter a hex value in the Value column or toggle the bit
values in the bit-n column. To read and write the values, the user changes can be updated one of two
modes:
Immediate — Whenever any of the memory map cells are changed, the GUI automatically and instantly
writes to the modified register, and updates the associated Device Setting pages. This update
mode is the default setting of the Memory Map page.
Manual — All changes applied to the grid are queued on the Memory Map page only. To update the
TUSS44x0 device with the changes, the Write All or Write Single buttons must be clicked.
A row on the Memory Map page highlighted blue indicates a selected row. A row on the Memory Map
page highlighted yellow indicates a queued modification to the grid, but a pending write to the TUSS44x0
device.
For a selected row, the register details are listed in the Register tab of the right panel. For details about
the Register Details tab, see Section 3.5.4.1 .
3.5.4.1 Register Details
This tab displays the detailed register information for the selected memory-map register row. The
operation, configurability, bit definitions, and related registers are described in this window. The Search
Registers refers to the same detailed library that the
Details window loads from.
3.5.4.1.1 Register Search
The Search Registers function allows the user to type in a keyword which is then compared to a library of
detailed register descriptions. The register address and full description containing the keyword are listed
as a result. Multiple registers may contain cross-references to the keyword, and thus multiple registers can
be listed as results.
3.6 TUSS44x0 GUI Right Panel
The right panel of the GUI serves as a support panel to update the user of device faults, provide
calculators and converters, log GUI activities, search register descriptions for keywords, and list the
detailed description of a selected register of the
Memory Map page. The right panel is not required to use
the GUI. The option to collapse this panel is made available under the View settings in the menu. The
right panel can also be resized manually.
3.6.1 Utilities
The Utilities tab offers additional tools to help the user search for and calculate values that pertain
specifically to ultrasonic time-of-flight and the TUSS44x0 device (see Figure 19 ).
