Hi all,

during a debugging session, the OSCx setting does not make any difference, as the device under test is always externally clocked from the SX-Key through the OSC1 pin with the internal clock oscillator turned off, as the OSC2 pin is required for the communication between the SX-Key and the SX under test.

When running stand-alone, it might be necessary to increase the internal oscillator driver gain by selecting a higher OSXxxx setting at lower supply voltages, but this also depends on the resonator/xtal type you are using. You also should consider selecting a higher gain in case the running system might be exposed to lower environmental temperatures.

Sorry, I forgot to mention the brownout setting before, because I thought this was obvious. No matter if you are debugging or run the chip stand-alone - you must always set the brownout level to a value lower than the supply voltage, or turn it completely off.

[/quote]I knew the chip wouldn't run with the brownout too high, I just didn't know what the debugger would do. The debugger in fact does state the the chip is "Running", when in fact it is not...   ...again, the results are very similar to my previous problems...
