6 Controlling the PGA400-Q1 Memory Spaces with the GUI
The PGA400-Q1 EVM is controlled by the user through a PC with the TI-GER USB
communication board and associated GUI. The PGA400-Q1 EVM GUI provides ways to
manipulate all of the register spaces present inside the PGA400-Q1 (TEST, ESFR, EEPROM,
IRAM, OTP). The following sections describe how to manipulate the register spaces.
6.1 Using the Register Grids to Manipulate the Register Spaces
Most of the register spaces have register grids associated with them that provide a simple way
to read/write the registers in the grid. There are eight buttons that are associated with the grid
operations: “ZERO GRID”, “DESELECT GRID”, “SAVE GRID”, RECALL GRID”, “READ
SELECTED”, “WRITE SELECTED”, “READ ALL”, and “WRITE ALL”. These buttons perform
operations on whichever register grid is currently displayed. For example, when the GUI first
loads the “TEST” register tab is displayed, if any of the previously listed buttons are pressed they
will perform operations on the “TEST” register space. Each of the GRID functions are described
below.
6.1.1 ZERO GRID
The “ZERO GRID” button will replace the contents of the entire grid with “0”.
6.1.2 DESELECT GRID
The “DESELECT GRID” button will remove any selections that have been made in the grid
without performing any operations on the registers that were selected.
