Stefan Ritt | Waveform Truncation Near the Cell0-Cell1023 Boundary in DRS4 ROI Readout Mode | The DRS4 gets into the "1.8A"
state if DSPEED approaches like 0.7V. Then
both inverters of the Domino chain are kind |

Stefan Ritt | Waveform Truncation Near the Cell0-Cell1023 Boundary in DRS4 ROI Readout Mode | Not much I can say here. I know that the
DRS4 works reliably, since we have an experiment
here with 500 chips running since 5 years |

Stefan Ritt | Waveform Truncation Near the Cell0-Cell1023 Boundary in DRS4 ROI Readout Mode | Actually looking at your waveforms again,
I think I understand maybe your problem.
You stop the DRS4 randomly, but your ROI |

Stefan Ritt | Waveform Truncation Near the Cell0-Cell1023 Boundary in DRS4 ROI Readout Mode | Does this happen with your own hardware
or with the DRS4 evaluation board? If it's
your own hardware, do you read out all 1024 |

I ported the drs4_eval5_app code
onto our board and observed much the same |

Stefan Ritt | Wrong Firmware Version: board has 13279, required is 15147. Board may not work properly | You have to use the software belonging
to that board. You cannot use the newest
software with an old board. Look here: |

Stefan Ritt | Handling of Write Shift Register and Write Config Register | Yes this is correct. Anyhow, even if it
would be working, you would not be happy
with it. After having designed ~10 boards |

Stefan Ritt | Clarification of full channel readout | The full readout mode is not really recommended
since you have to pull out the stop position
separately. Just do the ROI readout using |

Stefan Ritt | Handling of Write Shift Register and Write Config Register | This is correct. Setting A0-A3 to 0b1101
multiplexes the Shift Write Register to SROUT,
so you will either a "0" or a "1" |
