2.6. Device Version
2.7. Debugging Application which Drives LED
To maximize utilization of the package pins, the LED current driver output is shared with the debug chain clock
signal C2CLK. To share the functionality and be able to use the IDE for debugging there are some limitations to
note and rules to follow. The following figure shows the recommended connection of the USB 10-pin debug header
to the device in the user application.
Note: The LED must be isolated by the 470  resistor for the debug chain to work.
1. The device ID information can be read through the IDE through Views  Debug Windows  Si4010 
2. The trim version can be read by the Silicon Labs IDE as External Memory through Views  Debug Win-
XREG Regs. The last item bREV_ID is the device revision. The user can also call the API function
bSys_GetRevId().
dows -> External Memory at location 0x11D6. There is a macro bSys_TrimId_c defined in the headers
for use in customer code as well. The user needs to know the TrimId before writing any code, so the man-
ual access to it is adequate. The trim version will rarely change and customers will be notified about the
change.The provided NVM burner program reads both the bREV_ID device revision and the trim version
bSys_TrimId in the [Device] tab after the burner is connected to the device.
