After powering up HX2VL, sometimes OSC stops oscillating even though reset has not been applied. Can a device actively stop OSC? If so, what are the factors?

I think the internal logic is not working at all because the OSC is stuck. Is this correct?

Thanks,

Hi,

>> Could you please let us know if you are using a custom board or our DVK?

>> Is the behaviour afterwards normal or any abnormalities are seen?

>> Are you using in bus-power or self-power?

Regards,

Mallika

Mallika-san,

It is a custom board.

Power mode is self-powered mode. Power is supplied from DCDC on the board. HX2VL is always ON when the system is ON.

HX2VL is working normally.

Thanks,
Tetsuo
