Hi, Richard:
Based on the answer, that means, to get SYNCIN input, instead of a periodic divide-by-32-counter sourced from CLKIN, we can use a simple one-time-rising-edge-generator ( such as a schemitt-type input gate sourced from a power supply by a certain time delay to ensure that all circuits are in stable state), and get this one-time-rising-edge connected to SYNCIN to reset all internal logic and SYNCOUT counter?
Thanks.
