View Ref-FileFrame Rate Divider Control (DC4-DC0) CRA Bits 8-12:

   The DC4-DC0 bits control the divide ratio for the programable frame rate
dividers used to generate the frame clocks. In network mode, this ratio may
be interpreted as the number of words per frame minus one. In normal mode,
this ratio determines the word transfer rate. The divide ratio may range
from 1 to 32 (DC = 00000 to 11111) for normal mode and 2-32 (DC = 00001 to
11111) for network mode.

A divide ratio one (DC = 00000) in network mode is a special case. In normal
mode, a divide ratio of one (DC = 00000) provides continuous periodic data
word transfers. A bit-length sync (FSL1) = 1, FSL0 = 0) must be used in this
case. Hardware and software reset clear DC4-DC0.
