The user can perform the following in the IB File tab:

• Read the IB (1) File to IB Buffer(2)
• Save IB Buffer into the IB File
• From the "IB Type" drop-down list, select Flash (default value).
• Read the IB from DUT into the IB Buffer
• Commit the IB Buffer into DUT – the IB is stored in the Flash

Note:

1. Use the Information Block (IB) to store various types of calibration and system configuration information.
2. The IB Buffer is a temporary PC location for the Information Block (IB).

4.3.5 MAC Address Programming

In this demonstration, the user can set the Bluetooth Address and Zigbee MAC Address of the PIC32CX-BZ2 using a PC with the MCHPRT3 tool installed.

In the MAC Address tab, perform the following steps for MAC Address programming:

1. From the "IB Type" drop-down list, select Flash (default value).
2. To read the Bluetooth address from the IB, click Read BT Addr from IB.
3. To write the Bluetooth address:

a. Click Write BT Addr to IB Buffer.
b. Click Commit BT Addr IB Buffer to IB.

1. To read Zigbee MAC address from IB, click Read ZB Addr from IB.
2. To write Zigbee MC address:

a. Click Write ZB Addr to IB Buffer.
b. Click Commit ZB Addr IB Buffer to IB.

4.3.6 GPIO Demonstration

In this demonstration, the user can configure or test the GPIO of the PIC32CX-BZ2 using a PC with the installed MCHPRT3 tool.

In the GPIO tab, perform the following steps for GPIO Demonstration (see the following figure):

1. Click Start GPIO Test to initiate the GPIO settings for configuration or test.
2. Select "Port", "Pin", "In/Out" and "Level" to configure or test the GPIO pins.
3. Click Run to apply the GPIO configuration.
4. Repeat step 2 and 3 to perform a new GPIO configuration or test.
5. Click Stop GPIO Test to stop the GPIO settings for configuration or test.
6. Check the checkbox on each item to perform multiple GPIO configurations. Click Run All Select GPIO to apply all the selected GPIO configuration.
