Frame Length Timing Value (FLTV):
SOF micro-frame length) is equal to 59488 +
value in this field. The default value is decimal 32 (20h), which gives a SOF cycle time of
60000. Frame Length (number of High Speed bit times) FLADJ Value (decimal)

(20h) ... 60480 62 (3Eh) 60496 63 (3Fh) Each decimal value change to this register
corresponds to 16 high-speed bit times. The SOF cycle time (number of SOF counter
clock periods to generate a SOF micro-frame length) is equal to 59488 + value in this
field. The default value is decimal 32 (20h), which gives a SOF cycle time of 60000.
