13.6.1
These nine bits define the delay, in channel numbers, the serial interface receiver takes to store the channel
data from the Backplane stream input pins. The input channel delay can be set to 511 (32Mb/s streams), 255
(16Mb/s streams), 127 (8Mb/s streams), 63 (4Mb/s streams) or 31 (2Mb/s streams) from the frame boundary.
