Sync. Clock Phase Timing
M66239FP is able to control the phase of sync clock outputs (CKO, CKOB, PULSE) as each T/8 step. (T: clock period)
This phase shift control is set up by serial input resister No. 13.
Also, 1st edge phase (= (1) position) of sync clock outputs is not shifted, and 2nd edge phase (= (2) position) of sync
clock outputs is either not shifted position or resister set position, after 3rd edge phase (= (3) position) of sync clock
outputs is shift as resister settings.
CLKO output can not use this phase shift function because CLKO is asynchronous clock output to trigger.

2.
1st edge phase of sync clock output is not shifted.
2nd edge phase of sync clock output is either not shifted position or resistor set position,
3rd edge phase of sync clock output is shift as resistor settings.
It can set T/8 step resolution, but if T/8 is less than synchronizing precision (jitter)
+/– 1.5 ns, it may be not able to realize such high step resolution.
T/8 is not guarantee value which is taken into account the jitter and noise.
