If multiple AS1109 devices are cascaded and t r or t f is large, it may be critical to achieve the timing required for data transfer between two
cascaded LED drivers.
Note: All limits are guaranteed. The parameters with min and max values are guaranteed with production tests or SQC (Statistical Quality
Control) methods.
