First Frame
D[13:6]
Bits 7-0
Data length ranges from 10 to 14 bits. Data is sent starting with D13, and any unused trailing bits are set to 0.
Data requested in the preceding command frame is sent in the order shown below, with the data request of
highest priority is sent in the first two data frames, and any lower-priority requests sent in order in following
two-frame sets.
