Tool/software:
Hi,
I am having trouble to find out how exactly to use the SYNCIN signal. The EVAL board
user guide mentions absolutely nothing about it.
I found 2 versions of the data sheet. On the older one, it mentions register "x30",
bit "D5" to enable/disable it. If enabled, the SYNCIN is active low (page #8).
On the newer data sheet, there is no more mentioning of register "x30", but there
is still a graph to show that the SYNCIN is active high (page #31).
I guess, this SYNC input enables the user to pick which clock cycle to take the
data. What should I do if I would like to SYNC / start with a particular clock cycle,
then keep going? Do I need to maintain SYNCIN high?
In this case (start, keep going for some time), my SYNCIN can be a rather low
frequency signal. Can I use single end? Like tie SYNCINM to ground, only
pulse SYNCINP?
And, is register "x30" still available?
Thank you very much for helping. Best regards,
Dehong
