Set to the following value for resister 1.
For operation mode 1: "0000000000000001"
For operation mode 2: "0000000000000010"
For operation mode 3: "0000000000000011"
For operation mode 4: "0000000000000100"
Resister 12 must not change.
Above table intend to setting available value of resister, practical limits are described in page 20.
Resister 13 is for phase control of sync clock output.
If the default value of above resister use, write operation to all resister must be done.
Resister 6 to 9 refer to following.
1st Pole = Tspace1
2nd Pole = Tspace1 + Tspace2
3rd Pole = Tspace1 + Tspace2 + Tspace3
4th Pole = Tspace1 + Tspace2 + Tspace3 + Tspace4
