SCET timestamp trigger sourcesSome of the peripherals in the SoC have the capability of sending a timestamp trigger signalon specific events. These signals are routed to the SCET which has a number of generalpurpose trigger registers (GP) where a snapshot of the SCET counter is stored for laterretrieval by application software, see chapter 5.4. The tables below detail the mappingbetween the trigger signals and the general purpose trigger registers in the two products.Table 8-3 General purpose trigger mapGP number Trigger source Description0 power_loss Triggered when the voltage drops below a certain level, i.e. power islost to the board1 ccsds Triggered when telemetry sending on virtual channel 0 starts(Sirius TCM only)2 gpio Triggered when one of the pins input changes states and edgedetection and timestamping are enabled3 adc Triggered when an ADC conversion is started |
