looks are specified by an enumerated value (such as 0, 1, 2, 3).
Sequences are specified by an enumerated value (that is, 0, 1, 2, 3, and so forth) , and the value returned by this command is the sequence currently selected by the look algorithm when this command is received.
The current sequence frame rate is returned as a count that is 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 controller software made the sequence/duty cycle selection, or the user made the selection. The frame rate is specified in this way to enable fast and simple comparisons to the frame count by the software.
