Register block

Fields§

§tasks_start: TASKS_START

0x00 - Starts the SAADC and prepares the result buffer in RAM

§tasks_sample: TASKS_SAMPLE

0x04 - Takes one SAADC sample

§tasks_stop: TASKS_STOP

0x08 - Stops the SAADC and terminates all on-going conversions

§tasks_calibrateoffset: TASKS_CALIBRATEOFFSET

0x0c - Starts offset auto-calibration

§events_started: EVENTS_STARTED

0x100 - The SAADC has started

§events_end: EVENTS_END

0x104 - The SAADC has filled up the result buffer

§events_done: EVENTS_DONE

0x108 - A conversion task has been completed. Depending on the configuration, multiple conversions might be needed for a result to be transferred to RAM.

§events_resultdone: EVENTS_RESULTDONE

0x10c - Result ready for transfer to RAM

§events_calibratedone: EVENTS_CALIBRATEDONE

0x110 - Calibration is complete

§events_stopped: EVENTS_STOPPED

0x114 - The SAADC has stopped

§events_ch: [EVENTS_CH; 8]

0x118..0x158 - Unspecified

§inten: INTEN

0x300 - Enable or disable interrupt

§intenset: INTENSET

0x304 - Enable interrupt

§intenclr: INTENCLR

0x308 - Disable interrupt

§status: STATUS

0x400 - Status

§enable: ENABLE

0x500 - Enable or disable SAADC

§ch: [CH; 8]

0x510..0x590 - Unspecified

§resolution: RESOLUTION

0x5f0 - Resolution configuration

§oversample: OVERSAMPLE

0x5f4 - Oversampling configuration. The RESOLUTION is applied before averaging, thus for high OVERSAMPLE a higher RESOLUTION should be used.

§samplerate: SAMPLERATE

0x5f8 - Controls normal or continuous sample rate

§result: RESULT

0x62c..0x638 - RESULT EasyDMA channel
