82P33731/33831 EVALUATION BOARD
Before making a USB/I2C connection to the board, all configurations discussed in Step 1~8 above are stored in GUI until
the board is connected and configuration data are written to the device. Once the board is connected, by default, any
changes to the GUI configurations will be instantaneously written to the respective registers unless this feature is turned
off. See
Figure 19
below to turn on or off “Write changes to the chip immediately”.
Figure 19. By default, any modifications to the existing configuration data will be written to the device
registers immediately
If the feature is turned off, changes in configurations will be written to the chip by clicking on “Writing all registers to the
chip” button.

Writing to APLL3 related-registers.
The step described above will connect to the device and write to all registers
EXCEPT APLL3-related registers. In order to write APLL3 registers, take the following steps:
◦
Click on the top, left corner where device part number is displayed. Click on the first symbol (“Opening Setting File” is
shown when the mouse hovers on it). A window to open Personality File and Setting File pops out. See
Figure 20
below. Note: (1) un-check “Write to a trace file” box (green oval in the figure below); (2) use the same setting file
where all frequencies are configured (including APLL3); for Personality file, use the file that is solely for APLL3 (see
red oval in the following figure).
