Arbitration Configuration Register
| ANONC | Analog Converter Control |
| ARBRND | Arbitration Round Length 0 (value1): 4 arbitration slots per round (tARB = 4 / fADCD) 1 (value2): 8 arbitration slots per round (tARB = 8 / fADCD) 2 (value3): 16 arbitration slots per round (tARB = 16 / fADCD) 3 (value4): 20 arbitration slots per round (tARB = 20 / fADCD) |
| ARBM | Arbitration Mode 0 (value1): The arbiter runs permanently. This setting is required for a synchronization slave (see ) and for equidistant sampling using the signal ARBCNT (see ). 1 (value2): The arbiter only runs if at least one conversion request of an enabled request source is pending. This setting ensures a reproducible latency from an incoming request to the conversion start, if the converter is idle. Synchronized conversions are not supported. |
| ANONS | Analog Converter Control Status 0 (value1): Analog converter off 2 (value3): Slow standby mode 3 (value4): Normal operation (permanently on) |
| CSRC | Currently Converted Request Source 0 (value1): Current/last conversion for request source 0 1 (value2): Current/last conversion for request source 1 2 (value3): Current/last conversion for background source 3 (value4): Current/last conversion for synchronization request (slave converter) |
| CHNR | Channel Number |
| SYNRUN | Synchronous Conversion Running 0 (value1): Normal conversion or no conversion running 1 (value2): A synchronized conversion is running (cannot be cancelled by higher priority requests!) |
| CAL | Start-Up Calibration Active Indication 0 (value1): Completed or not yet started 1 (value2): Start-up calibration phase is active (set one clock cycle after setting bit SUCAL) |
| CALS | Start-Up Calibration Started 0 (value1): Requested but not yet started 1 (value2): Start-up calibration has begun |
| BUSY | Converter Busy Flag 0 (value1): Not busy 1 (value2): Converter is busy with a conversion |
| SAMPLE | Sample Phase Flag 0 (value1): Converting or idle 1 (value2): Input signal is currently sampled |
