The sequence header data is stored in two separate flash data structures (the Look structure and the sequence structure), and the values from each must match.

The bit weight and bit order for the duty cycle data is shown in Table 3-26.

The duty cycle data is specified as each color percent of the frame time. The sum of the three duty cycles must add up to 100. An example possibility is, R = 30.5 = 1E80h, G = 50 = 3200h, and B = 19.5 = 1380h)

The sequence maximum and minimum frame counts are specified in units of 66.67 ns. This is based on the internal 15-MHz clock used to time between input frame syncs. The frame rate is specified in this manner to enable the software to make quick and simple comparisons to the frame count.

The maximum number of sequence vectors byte is defined in Table 3-27.
