SET_UPDATE_TO_CAPTURE_INTERVAL

The SET_UPDATE_TO_CAPTURE_INTERVAL function is used to set a minimum interval between a scan update (change in output) and the next scan capture (read). This value is used between all types of scans - JTAG, PIO and external hardware that can be synchronised. It is guaranteed the interval will never be less than the value set.

The initial minimum interval is defined on the General Settings panel of the Advanced Configuration Options tab. Calling SET_UPDATE_TO_CAPTURE_INTERVAL will override the project setting, applying the given minimum interval. Later calls to RESET_UPDATE_TO_CAPTURE_INTERVAL reset the minimum interval back to the project setting.

SET_UPDATE_TO_CAPTURE_INTERVAL was added in XJTAG v4.1 and is not recognised in versions prior to that.
