DDC264: DDC264EVM: Hardware Trigger for the DDC264EVM

Part Number: DDC264


I use the DDC264EVM. I would like to use the Hardware trigger and in the DDC264EVM datasheet  the comment is:

HARDWARE TRIGGER: In normal operation, this should be Disabled. If Enabled, a pulse can be

issued on J4 to start a conversion after Fast Data is pressed. If enabled and no pulse ever comes, the

program appears to be frozen. If this condition happens, disable, cancel out the error messages, and


Please, can you give me some informations about:

- When the Hardware trigger is Enabled, this fonction  is-it active in this evaluation board?

- what is the amplitude and shape form of the input trigger signal on J4 connector?

Best regards.
