Preparing for Download and Verification

When you invoke the Hardware Debugger, the cable you installed is automatically detected. To modify the Communications settings, refer to the “Setting the Cable Options” section of the “Connecting Your Cable” chapter.

Checking the Logic Level of Pins

The Logic Level of Pins command allows you to use the XChecker cable to display the logic levels of the cable pins and probe digital signals on your board. It indicates the 1 or 0 value on each pin.

WARNING

Do not connect the XChecker leads to signals of different voltage levels than required because XChecker internal hardware damage can occur.

1. Connect the flying lead connector or header connector to the XChecker cable.
   
   
2. Attach the connectors from the flying lead connector or header connector to the pins or probe points.
   
   
3. Select Cable Logic Level of Pins.
   
   Before configuration, the following should be true: INIT=1, PROG=1, D/P=0, CCLK=1, and DIN=1.
   
   
4. Select Scan Status Constantly if you want the software to continually scan and update the status of the cable pins.
   
   
5. If necessary, make changes to the pin configuration.
