i want to konw to acquire a new data from SDADC , Whether need reset_key everyonce ？if need reset, required startup time 100 us min？
Hi, this RESET_KEY, when written with 0x5AF0, is used to generate the reset for SDADC block and to reload the internal counter with start value as programmed in OSDR.
There is no need to perform reset unless you are changing channel or other SDADC configuration. If you are converting only one channel, it is enough to repeat steps 7-8 (Considering 18.104.22.168 Data conversion step).
