ADC_MODE=OFF
ADC Control
ADC_TIME | ADC timing -1 in csd_sense clock cycles (actual time is ADC_TIME+1 cycles), either used to discharge Cref1&2, or as the aperture to capture the input voltage on Cref1&2 |
ADC_MODE | Enable ADC measurement. When enabled the ADC sequencer will be started when the main sequencer goes to the SAMPLE_NORM state 0 (OFF): No ADC measurement 1 (VREF_CNT): Count time A to bring Cref1 + Cref2 up from Vssa to Vrefhi with IDACB 2 (VREF_BY2_CNT): Count time B to bring Cref1 + Cref2 back up to Vrefhi with IDACB (after bringing them down for time A/2 cycles with IDACB sinking) 3 (VIN_CNT): Determine HSCMP polarity and count time C to source/sink Cref1 + Cref2 from Vin to Vrefhi. |
