Address H’F5 sets the DLL delay time and selects the 1/4 phase. Details are on the next page. And D15 of address
H’F8 can switch 2/3 divided mode but ensure that this address data relative to valid/invalid.

Phase settings of high speed pulse (address H’F5 to H’F8)
(1) Select the 1/4 phase from figure 13 at 2 divided mode (D15 = 0 of address H’F8).
Select the 1/6 phase from figure 14 at 3 divided mode (D15 = 1 of address H’F8).
·····P_SP1, P_SP2, P_ADCLK, P_RG
(2) Then select the necessary delay time from figure 15.
·····DL_SP1, DL_SP2, DL_RG, DL_ADCLK
RG can be set both of rising / falling edge optionally.
