Figure 3-99 shows the DPLL output-frequency change.
Figure 3-99 DPLL Output-Frequency ChangeTo unlock a DPLL, a mode different from the Lock Mode (0x7) should be programmed in the CM_CLKMODE_<DPLL NAME>[2:0] DPLL_EN bit field. The modes that can be programmed in the DPLL_EN bit field and can unlock the DPLL are:
Table 3-439 and Table 3-440 summarize register and subprocess call sequences for DPLL output frequency changes.
