Looks are specified by an enumerated value (such as 0, 1, 2, 3).
The current sequence frame rate is returned as a count specified in units of 66.67 ns (based on the internal 15-MHz clock used to time between input frame syncs), and is valid regardless of whether the controller software made the sequence or duty cycle selection. The frame rate is specified in this way to enable fast and simple compares to the frame count by the software.
