I have same questions about EXT_SYNC=01 Mode of ADXL355.
Could you please advise me timing specification about the external sync signal? Are there any constraint about the sync signal?
According to the datasheet of ADXL355, EXT_SYNC=01 mode can be used with only a single sync pulse. Can we send only one
sync pulse for synchronization in this case? Or should we send sync pulse continuously?
