Registers

Start the ADC and prepare the result buffer in RAM

Take one ADC sample, if scan is enabled all channels are sampled. This task requires that SAADC has started, i.e. EVENTS_STARTED was set and EVENTS_STOPPED was not.

Stop the ADC and terminate any on-going conversion

Starts offset auto-calibration

Subscribe configuration for task START

Subscribe configuration for task SAMPLE

Subscribe configuration for task STOP

Subscribe configuration for task CALIBRATEOFFSET

The ADC DMA has started

The ADC has filled up the Result buffer

A conversion task has been completed. Depending on the mode, multiple conversions might be needed for a result to be transferred to RAM.

A result is ready to get transferred to RAM.

Calibration is complete

The ADC DMA has stopped

Last results is above CH[n].LIMIT.HIGH

Last results is below CH[n].LIMIT.LOW

High/low limits for event monitoring a channel

Enable burst mode

Resolution configuration

Oversampling configuration. OVERSAMPLE should not be combined with SCAN unless burst is enabled. The RESOLUTION is applied before averaging, thus for high OVERSAMPLE a higher RESOLUTION should be used.

Configures the sampling rate for either task-triggered or continuous operation using a local timer

Data pointer

Maximum number of buffer bytes to transfer. Note that one sample is two bytes.

Number of buffer bytes transferred since last START, updated after the END or STOPPED events

Number of buffer bytes transferred since last START, continuously updated

SAADC provides two operational noise shaping modes (one that prioritizes higher bandwith, while the other prioritizes higher accuracy) that allow trade-offs between ADC resolution, power consumption, and signal bandwidth.
