I have a question about using the write config register to enable/disable sampling on the fly. I am looking to instrument an experiment at EPFL where multiple short events need to be captured during a 20us period followed by an 80us quiet period during which we could read out the chip. Would it be possible to start an acquisition with all channels seeing the same signal and the write config register set to 111111111 and then shift a zero into the write config reg after each event is detected to freeze the channels in time one-by-one? In this way we could measure up to 8 different events during the active period and then read them all out together during the quiet period. I have read the posts about the simultaneous read-write mode and the issue with waveforms stopping at cell 767. not knowing the exact details of what causes this issue I wonder if it would effect this sort of operation? Also, I would like to know if dwrite must be de-asserted while the write config register is being updated or if it could be done while the sampling is active? The latter would obviously be preferable as we would not incur any dead-time during the active period.
Thanks in advance for the information,
