MAVG_INV |
rw |
0 |
Invert the state of the moving average filter jumper (M4). This allows one to enable/disable moving average filter through software. 0 = non-inverted or normal operation (default) 1 = invert state of jumper to enable/disable moving average filter function. Observe the state at General Configuration Register. If the M4J bit is set in the General Configuration Register, then the moving average filter is enabled. |

SAIFTTS |
rw |
0 |
Sync Analog Input Frame Timer to Trigger Start. If set, then also moves the first sample to just after the trigger start rather than sampling at any time (i.e. 0 to 1 sample interval) after the trigger start. 0 = disabled (default). Timing between samples remains fixed regardless of point of trigger. 1 = Clear Analog Input Frame Timer upon Trigger Start. Sampling begins just after the trigger-start, thus synchronizing the sampling to the trigger start. |

SAIFCTS |

nSGATE |

Sampling Gate 0 = Ignore triggering subsystem (default) 1 = Use triggering subsystem for ADC-sampling |

AISS[3:0] |

0000 |
Analog Input Sampling Sources. This select the signal that is used to generate ADC-samples or ADC-bursts. 0000 = use ALSS[1:0] configuration (default, legacy ADC-sampling/-burst source) 0001 = Analog Input Sample/Frame Timer. 0010 = Interrupt Threshold Counter 0011 = none 0100 = none 0101 = none 0110 = none 0111 = none 1000 = DIN0 rising edge 1001 = DIN0 falling edge 1010 = DIN1 rising edge 1011 = DIN1 falling edge 1100 = DIN2 rising edge 1101 = DIN2 falling edge 1110 = DIN3 rising edge 1111 = DIN3 falling edge |
The Analog Input General Configuration Register configures the source of ADC-sampling or ADC-burst signalling (in legacy terms it is the old ADC-triggering sources). Upon reset or power up it defaults to legacy mode of operation.
