Once all the configuration values have been initially programmed into the PRCM registers controlling DPLL_PCIE_REF (see Section 26.4.4.4.1.4.2), the PRCM.CM_CLKMODE_DPLL_PCIE_REF[2:0] DPLL_EN bit should be set to 0x7 to start the DPLL calibration and locking sequence. After performing the locking sequence a lock status is indicated for DPLL_PCIE_REF by PRCM.CM_IDLEST_DPLL_PCIE_REF[0] ST_DPLL_CLK bit asserted to 0b1.
