ETSNZ - How to clear a M340 CPU so that it is without any configuration.

There is no direct reset to factory option for M340 CPU's. The alternative way to clear any residing application are:
Option 1: Create a new dummy application (only with CPU in configuration) and download this into the system to overwrite the original application and configuration.
Option 2: More straightforward, carry out the application download using Unity Pro, interrupt (cancel) the process whilst in progress.The the CPU will revert back to a no config state.
