Forum Post: Problem with LMP90100 in single scan mode.

Hi Support,

After I configure the AFE for single scan mode, it immediately performs the conversion and asserts the DRDYB (D6).  I read the ADC_DOUT registers and discard the data (clearing the DRDYB).  From this point, I can't find a simple method of starting the conversion.  I've tried writing 0x1 to the ADC_RESTART, but that doesn't do anything.  It doesn't allow setting the CH_SCAN single scan mode a second time either.

Is there a way of synchronizing the conversion to an external event in single scan mode?

Cheers,
