I've noted an odd bug in the SAADC specifically with the Low Power Mode enabled. I used the SAADC to either gather data via Timer+PPI during a data collection mode, OR polling with triggering an SAADC Sample with nrfx_saadc_sample(). I've noticed that if I power cycle and program the board, if I manually trigger a measurement the callback is never triggered. If I restart the firmware this doesn't occur, only seen after a Power On Reset. This doesn't occur if I disable the Low Power Mode. I noted that there are some odd stipulations in the SAADC driver regarding manually triggering measurements, but this seems to be an odd bug. Is this expected behaviour? I use SDK15.2
