Controlling the PGA450-Q1 Memory Spaces With the GUI
The PGA450-Q1 EVM is controlled by the user through a PC with the USB communication board and
associated GUI. The PGA450-Q1 EVM GUI provides ways to manipulate all of the register spaces present
inside the PGA450-Q1 (ESFR, EEPROM, RAM, OTP, DEVELOPMENT RAM). The following sections
describe how to manipulate the register spaces.

describe how to manipulate the register spaces.
10.1 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 ESFR register tab is displayed, if any of the
previously listed buttons are pressed they perform operations on the ESFR register space. Each of the
GRID functions is in one of the following sections.

10.1.1
ZERO GRID
The ZERO GRID button replaces the contents of the entire grid with 0.
10.1.2
DESELECT GRID
The DESELECT GRID button removes any selections that have been made in the grid without performing
any operations on the registers that were selected.

10.1.3
SAVE GRID
The SAVE GRID button takes the contents of the register grid and saves them to a .TXT file. The data is
saved in comma-separated-values format.
saved in comma-separated-values format.
10.1.4
RECALL GRID
The RECALL GRID button opens a prompt that allows the user to select a .TXT file that was produced
during the SAVE GRID operation and then loads the grid with the contents from the .TXT file.

READ SELECTED
The READ SELECTED button performs a read operation on any registers in the grid that have been
selected by clicking the desired register number. Any selected registers are displayed blue.

10.1.6
WRITE SELECTED
The WRITE SELECTED button will perform a write operation on any registers in the grid that have been
selected by clicking the register number or modifying the register contents. Any selected registers are
displayed in blue and any modified registers are highlighted in yellow. Any blue or yellow registers are
written to when the WRITE SELECTED button is pressed.

10.1.7
READ ALL
The READ ALL button performs a read operation on every register in the grid.
