USING THE EVALUATION BOARD TO PROGRAM AN
This guide shows how to use an
program an AD9520 on the board designed by the user board

via the I C interface. It assumes that the user has access to the
2
I C pins via a header on the target board, and knows the
assigned address of the target I

3. Select the desired I C address for the
board using Jumper S5 and Jumper S6. Note that the S5 =
S6 = high setting is reserved for SPI mode. Also, this I
address must not conflict with the I
AD9520.
4. Attach a jumper cable from SDIO_SDA pin of Header P1
of the evaluation board to the SDA pin on the target board.
5. Repeat Step 4 for both the SCLK_SCL pin and GND pin of
the AD9520 evaluation board to the SCL pin and ground
pin of the target board, respectively. On the evaluation
software, select Configure Serial Port from the I/O menu.
This window is shown in Figure 28.

6. Click Reset Serial Port and then click Detect Current
Configuration. A dialog box appears and acknowledges

the I C mode and address. The evaluation software starts at
2
I C Address 0x058 and stops at the first valid I
that it finds. If the target I
one automatically selected, select the I

click Debug. Click the I2C Debug button. The window
shown in Figure 29 appears.
