GreenPAK Serial Debugger/I2C

The GreenPAK Serial Debugger provides a simple I2C interface between the GreenPAK Designer

software and the AA PAK evaluation board. The GSD tool requires four signals as shown in Table 7.

These connections to the evaluation board can be made using either the P2 or the P3 headers.

The GSD comes equipped with two 1 k

Ω pull-up resistors. The R1 and R2 pull-up resistor footprints

on the AA PAK evaluation board provide additional flexibility for using an external I2C controller.

Follow the procedure below to connect the GreenPAK Designer software to the SLG47004 evaluation

board using the GSD:

1. Open an instance of the GreenPAK Designer software for the SLG47004.

2. Connect the GSD to your computer with the included USB cable.

3. Attach the GSD to the SLG47004 evaluation board using either the P2 or P3 headers.

4.

Open the “Debug” tool within the GreenPAK Designer software and select the “GreenPAK Serial

Debugger”. If the window in Figure 2 does not appear, click the “Change Platform” button in the

“Debugging Controls” window.

5.

Change the “Device:” dropdown selection to either “Auto Detect” or to the appropriate external I2C

control code. By default, all SLG47004 devices are configured with a control code of 0001 which

corresponds to the “External: 0001” option in the list.

6.

Select “Int. VDD” to connect the GSD’s VDD signal generator to the evaluation board. The supply

voltage level can then be selected in the adjacent dropdown window. When using an external VDD

on the AA PAK evaluation board, make sure to select “Ext. VDD” in the “Debugging Controls”

window.

7. Click th

e “Emulation” or “Program” buttons to load the GreenPAK Designer’s current configuration

onto the SLG47004 device.

Figure 4

shows an example configuration for the “Debugging Controls” window while emulation is

running.
